[SPARK-11859][MESOS] SparkContext accepts invalid Master URLs in the form zk://host:port for a multi-master Mesos cluster using ZooKeeper * According to below doc and validation logic in [SparkSubmit.scala](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L231), master URL for a mesos cluster should always start with `mesos://` http://spark.apache.org/docs/latest/running-on-mesos.html `The Master URLs for Mesos are in the form mesos://host:5050 for a single-master Mesos cluster, or mesos://zk://host:2181 for a multi-master Mesos cluster using ZooKeeper.` * However, [SparkContext.scala](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L2749) fails the validation and can receive master URL in the form `zk://host:port` * For the master URLs in the form `zk:host:port`, the valid form should be `mesos://zk://host:port` * This PR restrict the validation in `SparkContext.scala`, and now only mesos master URLs prefixed with `mesos://` can be accepted. * This PR also updated corresponding unit test.

In https://github.com/apache/spark/pull/9409 we enabled multi-column counting. The approach taken in that PR introduces a bit of overhead by first creating a row only to check if all of the columns are non-null. This PR fixes that technical debt. Count now takes multiple columns as its input. In order to make this work I have also added support for multiple columns in the single distinct code path. cc yhuai Author: Herman van Hovell <hvanhovell@questtec.nl> Closes #10015 from hvanhovell/SPARK-12024.

Change ```cumeDist -> cume_dist, denseRank -> dense_rank, percentRank -> percent_rank, rowNumber -> row_number``` at SparkR side. There are two reasons that we should make this change: * We should follow the [naming convention rule of R](http://www.inside-r.org/node/230645) * Spark DataFrame has deprecated the old convention (such as ```cumeDist```) and will remove it in Spark 2.0. It's better to fix this issue before 1.6 release, otherwise we will make breaking API change. cc shivaram sun-rui Author: Yanbo Liang <ybliang8@gmail.com> Closes #10016 from yanboliang/SPARK-12025.

In the previous implementation, the driver needs to know the executor listening address to send the thread dump request. However, in Netty RPC, the executor doesn't listen to any port, so the executor thread dump feature is broken. This patch makes the driver use the endpointRef stored in BlockManagerMasterEndpoint to send the thread dump request to fix it.

[SPARK-11998][SQL][TEST-HADOOP2.0] When downloading Hadoop artifacts from maven, we need to try to download the version that is used by Spark If we need to download Hive/Hadoop artifacts, try to download a Hadoop that matches the Hadoop used by Spark. If the Hadoop artifact cannot be resolved (e.g. Hadoop version is a vendor specific version like 2.0.0-cdh4.1.1), we will use Hadoop 2.4.0 (we used to hard code this version as the hadoop that we will download from maven) and we will not share Hadoop classes. I tested this match in my laptop with the following confs (these confs are used by our builds). All tests are good. ``` build/sbt -Phadoop-1 -Dhadoop.version=1.2.1 -Pkinesis-asl -Phive-thriftserver -Phive build/sbt -Phadoop-1 -Dhadoop.version=2.0.0-mr1-cdh4.1.1 -Pkinesis-asl -Phive-thriftserver -Phive build/sbt -Pyarn -Phadoop-2.2 -Pkinesis-asl -Phive-thriftserver -Phive build/sbt -Pyarn -Phadoop-2.3 -Dhadoop.version=2.3.0 -Pkinesis-asl -Phive-thriftserver -Phive ``` Author: Yin Huai <yhuai@databricks.com> Closes #9979 from yhuai/versionsSuite.

this is based on https://github.com/apache/spark/pull/9844, with some bug fix and clean up. The problems is that, normal operator should be resolved based on its child, but `Sort` operator can also be resolved based on its grandchild. So we have 3 rules that can resolve `Sort`: `ResolveReferences`, `ResolveSortReferences`(if grandchild is `Project`) and `ResolveAggregateFunctions`(if grandchild is `Aggregate`). For example, `select c1 as a , c2 as b from tab group by c1, c2 order by a, c2`, we need to resolve `a` and `c2` for `Sort`. Firstly `a` will be resolved in `ResolveReferences` based on its child, and when we reach `ResolveAggregateFunctions`, we will try to resolve both `a` and `c2` based on its grandchild, but failed because `a` is not a legal aggregate expression. whoever merge this PR, please give the credit to dilipbiswal Author: Dilip Biswal <dbiswal@us.ibm.com> Author: Wenchen Fan <wenchen@databricks.com> Closes #9961 from cloud-fan/sort.

In the previous codes, `newDaemonCachedThreadPool` uses `SynchronousQueue`, which is wrong. `SynchronousQueue` is an empty queue that cannot cache any task.

On the live web UI, there is a SQL tab which provides valuable information for the SQL query. But once the workload is finished, we won't see the SQL tab on the history server. It will be helpful if we support SQL UI on the history server so we can analyze it even after its execution. To support SQL UI on the history server: 1. I added an `onOtherEvent` method to the `SparkListener` trait and post all SQL related events to the same event bus. 2. Two SQL events `SparkListenerSQLExecutionStart` and `SparkListenerSQLExecutionEnd` are defined in the sql module. 3. The new SQL events are written to event log using Jackson. 4. A new trait `SparkHistoryListenerFactory` is added to allow the history server to feed events to the SQL history listener. The SQL implementation is loaded at runtime using `java.util.ServiceLoader`. Author: Carson Wang <carson.wang@intel.com> Closes #9297 from carsonwang/SqlHistoryUI.

This change does a couple of different things to make sure that the RpcEnv-level code and the network library agree about the status of outstanding RPCs. For RPCs that do not expect a reply ("RpcEnv.send"), support for one way messages (hello CORBA!) was added to the network layer. This is a "fire and forget" message that does not require any state to be kept by the TransportClient; as a result, the RpcEnv 'Ack' message is not needed anymore. For RPCs that do expect a reply ("RpcEnv.ask"), the network library now returns the internal RPC id; if the RpcEnv layer decides to time out the RPC before the network layer does, it now asks the TransportClient to forget about the RPC, so that if the network-level timeout occurs, the client is not killed. As part of implementing the above, I cleaned up some of the code in the netty rpc backend, removing types that were not necessary and factoring out some common code. Of interest is a slight change in the exceptions when posting messages to a stopped RpcEnv; that's mostly to avoid nasty error messages from the local-cluster backend when shutting down, which pollutes the terminal output.
