JIRA issues: - Main: [SPARK-2678](https://issues.apache.org/jira/browse/SPARK-2678) - Related: [SPARK-2874](https://issues.apache.org/jira/browse/SPARK-2874) Related PR: - #1715 This PR is both a fix for SPARK-2874 and a workaround for SPARK-2678. Fixing SPARK-2678 completely requires some API level changes that need further discussion, and we decided not to include it in Spark 1.1 release. As currently SPARK-2678 only affects Spark SQL scripts, this workaround is enough for Spark 1.1. Command line option handling logic in bash scripts looks somewhat dirty and duplicated, but it helps to provide a cleaner user interface as well as retain full downward compatibility for now.

The goal of this PR is to allow users of Spark to write tight firewall rules for their clusters. This is currently not possible because Spark uses random ports in many places, notably the communication between executors and drivers. The changes in this PR are based on top of ash211's changes in #1107. The list covered here may or may not be the complete set of port needed for Spark to operate perfectly. However, as of the latest commit there are no known sources of random ports (except in tests). I have not documented a few of the more obscure configs. My spark-env.sh looks like this: ``` export SPARK_MASTER_PORT=6060 export SPARK_WORKER_PORT=7070 export SPARK_MASTER_WEBUI_PORT=9090 export SPARK_WORKER_WEBUI_PORT=9091 ``` and my spark-defaults.conf looks like this: ``` spark.master spark://andrews-mbp:6060 spark.driver.port 5001 spark.fileserver.port 5011 spark.broadcast.port 5021 spark.replClassServer.port 5031 spark.blockManager.port 5041 spark.executor.port 5051 ``` Author: Andrew Or <andrewor14@gmail.com> Author: Andrew Ash <andrew@andrewash.com> Closes #1777 from andrewor14/configure-ports and squashes the following commits: 621267b [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 8a6b820 [Andrew Or] Use a random UI port during tests 7da0493 [Andrew Or] Fix tests 523c30e [Andrew Or] Add test for isBindCollision b97b02a [Andrew Or] Minor fixes c22ad00 [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 93d359f [Andrew Or] Executors connect to wrong port when collision occurs d502e5f [Andrew Or] Handle port collisions when creating Akka systems a2dd05c [Andrew Or] Patrick's comment nit 86461e2 [Andrew Or] Remove spark.executor.env.port and spark.standalone.client.port 1d2d5c6 [Andrew Or] Fix ports for standalone cluster mode cb3be88 [Andrew Or] Various doc fixes (broken link, format etc.) e837cde [Andrew Or] Remove outdated TODOs bfbab28 [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports de1b207 [Andrew Or] Update docs to reflect new ports b565079 [Andrew Or] Add spark.ports.maxRetries 2551eb2 [Andrew Or] Remove spark.worker.watcher.port 151327a [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 9868358 [Andrew Or] Add a few miscellaneous ports 6016e77 [Andrew Or] Add spark.executor.port 8d836e6 [Andrew Or] Also document SPARK_{MASTER/WORKER}_WEBUI_PORT 4d9e6f3 [Andrew Or] Fix super subtle bug 3f8e51b [Andrew Or] Correct erroneous docs... e111d08 [Andrew Or] Add names for UI services 470f38c [Andrew Or] Special case non-"Address already in use" exceptions 1d7e408 [Andrew Or] Treat 0 ports specially + return correct ConnectionManager port ba32280 [Andrew Or] Minor fixes 6b550b0 [Andrew Or] Assorted fixes 73fbe89 [Andrew Or] Move start service logic to Utils ec676f4 [Andrew Or] Merge branch 'SPARK-2157' of github.com:ash211/spark into configure-ports 038a579 [Andrew Ash] Trust the server start function to report the port the service started on 7c5bdc4 [Andrew Ash] Fix style issue 0347aef [Andrew Ash] Unify port fallback logic to a single place 24a4c32 [Andrew Ash] Remove type on val to match surrounding style 9e4ad96 [Andrew Ash] Reformat for style checker 5d84e0e [Andrew Ash] Document new port configuration options 066dc7a [Andrew Ash] Fix up HttpServer port increments cad16da [Andrew Ash] Add fallover increment logic for HttpServer c5a0568 [Andrew Ash] Fix ConnectionManager to retry with increment b80d2fd [Andrew Ash] Make Spark's block manager port configurable 17c79bb [Andrew Ash] Add a configuration option for spark-shell's class server f34115d [Andrew Ash] SPARK-1176 Add port configuration for HttpBroadcast 49ee29b [Andrew Ash] SPARK-1174 Add port configuration for HttpFileServer 1c0981a [Andrew Ash] Make port in HttpServer configurable

copied from original JIRA (https://issues.apache.org/jira/browse/SPARK-2294): If an executor E is free, a task may be speculatively assigned to E when there are other tasks in the job that have not been launched (at all) yet. Similarly, a task without any locality preferences may be assigned to E when there was another NODE_LOCAL task that could have been scheduled. This happens because TaskSchedulerImpl calls TaskSetManager.resourceOffer (which in turn calls TaskSetManager.findTask) with increasing locality levels, beginning with PROCESS_LOCAL, followed by NODE_LOCAL, and so on until the highest currently allowed level. Now, supposed NODE_LOCAL is the highest currently allowed locality level. The first time findTask is called, it will be called with max level PROCESS_LOCAL; if it cannot find any PROCESS_LOCAL tasks, it will try to schedule tasks with no locality preferences or speculative tasks. As a result, speculative tasks or tasks with no preferences may be scheduled instead of NODE_LOCAL tasks. ---- I added an additional parameter in resourceOffer and findTask, maxLocality, indicating when we should consider the tasks without locality preference Author: CodingCat <zhunansjtu@gmail.com> Closes #1313 from CodingCat/SPARK-2294 and squashes the following commits: bf3f13b [CodingCat] rollback some forgotten changes 89f9bc0 [CodingCat] address matei's comments 18cae02 [CodingCat] add test case for node-local tasks 2ba6195 [CodingCat] fix failed test cases 87dd09e [CodingCat] fix style 9b9432f [CodingCat] remove hasNodeLocalOnlyTasks fdd1573 [CodingCat] fix failed test cases 941a4fd [CodingCat] see my shocked face.......... f600085 [CodingCat] remove hasNodeLocalOnlyTasks checking 0b8a46b [CodingCat] test whether hasNodeLocalOnlyTasks affect the results 73ceda8 [CodingCat] style fix b3a430b [CodingCat] remove fine granularity tracking for node-local only tasks f9a2ad8 [CodingCat] simplify the logic in TaskSchedulerImpl c8c1de4 [CodingCat] simplify the patch be652ed [CodingCat] avoid unnecessary delay when we only have nopref tasks dee9e22 [CodingCat] fix locality inversion bug in TaskManager by moving nopref branch

[SPARK-2650][SQL] Try to partially fix SPARK-2650 by adjusting initial buffer size and reducing memory allocation JIRA issue: [SPARK-2650](https://issues.apache.org/jira/browse/SPARK-2650) Please refer to [comments](https://issues.apache.org/jira/browse/SPARK-2650?focusedCommentId=14084397&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14084397) of SPARK-2650 for some other details. This PR adjusts the initial in-memory columnar buffer size to 1MB, same as the default value of Shark's `shark.column.partitionSize.mb` property when running in local mode. Will add Shark style partition size estimation in another PR. Also, before this PR, `NullableColumnBuilder` copies the whole buffer to add the null positions section, and then `CompressibleColumnBuilder` copies and compresses the buffer again, even if compression is disabled (`PassThrough` compression scheme is used to disable compression). In this PR the first buffer copy is eliminated to reduce memory consumption.

This patch adds support for giving accumulators user-visible names and displaying accumulator values in the web UI. This allows users to create custom counters that can display in the UI. The current approach displays both the accumulator deltas caused by each task and a "current" value of the accumulator totals for each stage, which gets update as tasks finish. Currently in Spark developers have been extending the `TaskMetrics` functionality to provide custom instrumentation for RDD's. This provides a potentially nicer alternative of going through the existing accumulator framework (actually `TaskMetrics` and accumulators are on an awkward collision course as we add more features to the former). The current patch demo's how we can use the feature to provide instrumentation for RDD input sizes. The nice thing about going through accumulators is that users can read the current value of the data being tracked in their programs. This could be useful to e.g. decide to short-circuit a Spark stage depending on how things are going.

It was easier to combine these 2 jira since they touch many of the same places. This pr adds the following: - adds modify acls - adds admin acls (list of admins/users that get added to both view and modify acls) - modify Kill button on UI to take modify acls into account - changes config name of spark.ui.acls.enable to spark.acls.enable since I choose poorly in original name. We keep backwards compatibility so people can still use spark.ui.acls.enable. The acls should apply to any web ui as well as any CLI interfaces. - send view and modify acls information on to YARN so that YARN interfaces can use (yarn cli for killing applications for example).

This tracks memory properly if there are multiple spilling collections in the same task (which was a problem before), and also implements an algorithm that lets each thread grow up to 1 / 2N of the memory pool (where N is the number of threads) before spilling, which avoids an inefficiency with small spills we had before (some threads would spill many times at 0-1 MB because the pool was allocated elsewhere).

All these changes are from mridulm's work in #1609, but extracted here to fix this specific issue and make it easier to merge not 1.1. This particular set of changes is to make sure that we read exactly the right range of bytes from each spill file in EAOM: some serializers can write bytes after the last object (e.g. the TC_RESET flag in Java serialization) and that would confuse the previous code into reading it as part of the next batch. There are also improvements to cleanup to make sure files are closed.

This is a pull request regarding SPARK-2510 at https://issues.apache.org/jira/browse/SPARK-2510. Word2Vec creates vector representation of words in a text corpus. The algorithm first constructs a vocabulary from the corpus and then learns vector representation of words in the vocabulary. The vector representation can be used as features in natural language processing and machine learning algorithms. To make our implementation more scalable, we train each partition separately and merge the model of each partition after each iteration. To make the model more accurate, multiple iterations may be needed. To investigate the vector representations is to find the closest words for a query word. For example, the top 20 closest words to "china" are for 1 partition and 1 iteration : taiwan 0.8077646146334014 korea 0.740913304563621 japan 0.7240667798885471 republic 0.7107151279078352 thailand 0.6953217332072862 tibet 0.6916782118129544 mongolia 0.6800858715972612 macau 0.6794925677480378 singapore 0.6594048695593799 manchuria 0.658989931844148 laos 0.6512978726001666 nepal 0.6380792327845325 mainland 0.6365469459587788 myanmar 0.6358614338840394 macedonia 0.6322366180313249 xinjiang 0.6285291551708028 russia 0.6279951236068411 india 0.6272874944023487 shanghai 0.6234544135576999 macao 0.6220588462925876 The result with 10 partitions and 5 iterations is: taiwan 0.8310495079388313 india 0.7737171315919039 japan 0.756777901233668 korea 0.7429767187102452 indonesia 0.7407557427278356 pakistan 0.712883426985585 mainland 0.7053379963140822 thailand 0.696298191073948 mongolia 0.693690656871415 laos 0.6913069680735292 macau 0.6903427690029617 republic 0.6766381604813666 malaysia 0.676460699141784 singapore 0.6728790997360923 malaya 0.672345232966194 manchuria 0.6703732292753156 macedonia 0.6637955686322028 myanmar 0.6589462882439646 kazakhstan 0.657017801081494 cambodia 0.6542383836451932 Author: Liquan Pei <lpei@gopivotal.com> Author: Xiangrui Meng <meng@databricks.com> Author: Liquan Pei <liquanpei@gmail.com> Closes #1719 from Ishiihara/master and squashes the following commits: 2ba9483 [Liquan Pei] minor fix for Word2Vec test e248441 [Liquan Pei] minor style change 26a948d [Liquan Pei] Merge pull request #1 from mengxr/Ishiihara-master c14da41 [Xiangrui Meng] fix styles 384c771 [Xiangrui Meng] remove minCount and window from constructor change model to use float instead of double e93e726 [Liquan Pei] use treeAggregate instead of aggregate 1a8fb41 [Liquan Pei] use weighted sum in combOp 7efbb6f [Liquan Pei] use broadcast version of vocab in aggregate 6bcc8be [Liquan Pei] add multiple iteration support 720b5a3 [Liquan Pei] Add test for Word2Vec algorithm, minor fixes 2e92b59 [Liquan Pei] modify according to feedback 57dc50d [Liquan Pei] code formatting e4a04d3 [Liquan Pei] minor fix 0aafb1b [Liquan Pei] Add comments, minor fixes 8d6befe [Liquan Pei] initial commit

SPARK-2272 [MLlib] Feature scaling which standardizes the range of independent variables or features of data Feature scaling is a method used to standardize the range of independent variables or features of data. In data processing, it is generally performed during the data preprocessing step. In this work, a trait called `VectorTransformer` is defined for generic transformation on a vector. It contains one method to be implemented, `transform` which applies transformation on a vector. There are two implementations of `VectorTransformer` now, and they all can be easily extended with PMML transformation support. 1) `StandardScaler` - Standardizes features by removing the mean and scaling to unit variance using column summary statistics on the samples in the training set. 2) `Normalizer` - Normalizes samples individually to unit L^n norm Author: DB Tsai <dbtsai@alpinenow.com> Closes #1207 from dbtsai/dbtsai-feature-scaling and squashes the following commits: 78c15d3 [DB Tsai] Alpine Data Labs

Kill only the python worker related to cancelled tasks. The daemon will start a background thread to monitor all the opened sockets for all workers. If the socket is closed by JVM, this thread will kill the worker. When an task is cancelled, the socket to worker will be closed, then the worker will be killed by deamon. Author: Davies Liu <davies.liu@gmail.com> Closes #1643 from davies/kill and squashes the following commits: 8ffe9f3 [Davies Liu] kill worker by deamon, because runtime.exec() is too heavy 46ca150 [Davies Liu] address comment acd751c [Davies Liu] kill the worker when task is canceled
