Currently, all best splits are computed on the driver, which makes the driver a bottleneck for both communication and computation. This PR fix this problem by computed best splits on executors. Instead of send all aggregate stats to the driver node, we can send aggregate stats for a node to a particular executor, using `reduceByKey` operation, then we can compute best split for this node there. Implementation details: Each node now has a nodeStatsAggregator, which save aggregate stats for all features and bins. First use mapPartition to compute node aggregate stats for all nodes in each partition. Then transform node aggregate stats to (nodeIndex, nodeStatsAggregator) pairs and use to `reduceByKey` operation to combine nodeStatsAggregator for the same node. After all stats have been combined, best splits can be computed for each node based on the node aggregate stats. Best split result is collected to driver to construct the decision tree.

If you turn authentication on and you are using a lot of executors. There is a chance that all the of the threads in the handleMessageExecutor could be waiting to send a message because they are blocked waiting on authentication to happen. This can cause a temporary deadlock until the connection times out. To fix it, I got rid of the wait/notify and use a single outbox but only send security messages from it until authentication has completed.

[SPARK-3495] Block replication fails continuously when the replication target node is dead AND [SPARK-3496] Block replication by mistake chooses driver as target If a block manager (say, A) wants to replicate a block and the node chosen for replication (say, B) is dead, then the attempt to send the block to B fails. However, this continues to fail indefinitely. Even if the driver learns about the demise of the B, A continues to try replicating to B and failing miserably. The reason behind this bug is that A initially fetches a list of peers from the driver (when B was active), but never updates it after B is dead. This affects Spark Streaming as its receiver uses block replication. The solution in this patch adds the following. - Changed BlockManagerMaster to return all the peers of a block manager, rather than the requested number. It also filters out driver BlockManager. - Refactored BlockManager's replication code to handle peer caching correctly. + The peer for replication is randomly selected. This is different from past behavior where for a node A, a node B was deterministically chosen for the lifetime of the application. + If replication fails to one node, the peers are refetched. + The peer cached has a TTL of 1 second to enable discovery of new peers and using them for replication. - Refactored use of \<driver\> in BlockManager into a new method `BlockManagerId.isDriver` - Added replication unit tests (replication was not tested till now, duh!) This should not make a difference in performance of Spark workloads where replication is not used. @andrewor14 @JoshRosen Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #2366 from tdas/replication-fix and squashes the following commits: 9690f57 [Tathagata Das] Moved replication tests to a new BlockManagerReplicationSuite. 0661773 [Tathagata Das] Minor changes based on PR comments. a55a65c [Tathagata Das] Added a unit test to test replication behavior. 012afa3 [Tathagata Das] Bug fix 89f91a0 [Tathagata Das] Minor change. 68e2c72 [Tathagata Das] Made replication peer selection logic more efficient. 08afaa9 [Tathagata Das] Made peer selection for replication deterministic to block id 3821ab9 [Tathagata Das] Fixes based on PR comments. 08e5646 [Tathagata Das] More minor changes. d402506 [Tathagata Das] Fixed imports. 4a20531 [Tathagata Das] Filtered driver block manager from peer list, and also consolidated the use of <driver> in BlockManager. 7598f91 [Tathagata Das] Minor changes. 03de02d [Tathagata Das] Change replication logic to correctly refetch peers from master on failure and on new worker addition. d081bf6 [Tathagata Das] Fixed bug in get peers and unit tests to test get-peers and replication under executor churn. 9f0ac9f [Tathagata Das] Modified replication tests to fail on replication bug. af0c1da [Tathagata Das] Added replication unit tests to BlockManagerSuite -

### Problem The section "Using the shell" in Spark Programming Guide (https://spark.apache.org/docs/latest/programming-guide.html#using-the-shell) says that we can run pyspark REPL through IPython. But a folloing command does not run IPython but a default Python executable. ``` $ IPYTHON=1 ./bin/pyspark Python 2.7.8 (default, Jul 2 2014, 10:14:46) ... ``` the spark/bin/pyspark script on the commit b235e013 decides which executable and options it use folloing way. 1. if PYSPARK_PYTHON unset * → defaulting to "python" 2. if IPYTHON_OPTS set * → set IPYTHON "1" 3. some python scripts passed to ./bin/pyspak → run it with ./bin/spark-submit * out of this issues scope 4. if IPYTHON set as "1" * → execute $PYSPARK_PYTHON (default: ipython) with arguments $IPYTHON_OPTS * otherwise execute $PYSPARK_PYTHON Therefore, when PYSPARK_PYTHON is unset, python is executed though IPYTHON is "1". In other word, when PYSPARK_PYTHON is unset, IPYTHON_OPS and IPYTHON has no effect on decide which command to use. PYSPARK_PYTHON | IPYTHON_OPTS | IPYTHON | resulting command | expected command ---- | ---- | ----- | ----- | ----- (unset → defaults to python) | (unset) | (unset) | python | (same) (unset → defaults to python) | (unset) | 1 | python | ipython (unset → defaults to python) | an_option | (unset → set to 1) | python an_option | ipython an_option (unset → defaults to python) | an_option | 1 | python an_option | ipython an_option ipython | (unset) | (unset) | ipython | (same) ipython | (unset) | 1 | ipython | (same) ipython | an_option | (unset → set to 1) | ipython an_option | (same) ipython | an_option | 1 | ipython an_option | (same) ### Suggestion The pyspark script should determine firstly whether a user wants to run IPython or other executables. 1. if IPYTHON_OPTS set * set IPYTHON "1" 2. if IPYTHON has a value "1" * PYSPARK_PYTHON defaults to "ipython" if not set 3.

The following code gives error. ``` sqlContext.registerFunction("len", (s: String) => s.length) sqlContext.sql("select len(foo) as a, count(1) from t1 group by len(foo)").collect() ``` Because SQl parser creates the aliases to the functions in grouping expressions with generated alias names. So if user gives the alias names to the functions inside projection then it does not match the generated alias name of grouping expression. This kind of queries are working in Hive. So the fix I have given that if user provides alias to the function in projection then don't generate alias in grouping expression,use the same alias.

FutureAction is the only type exposed through the async APIs, so for job IDs to be useful they need to be exposed there. The complication is that some async jobs run more than one job (e.g. takeAsync), so the exposed ID has to actually be a list of IDs that can actually change over time. So the interface doesn't look very nice, but... Change is actually small, I just added a basic test to make sure it works.

This patch add profiling support for PySpark, it will show the profiling results before the driver exits, here is one example: ``` ============================================================ Profile of RDD<id=3> ============================================================ 5146507 function calls (5146487 primitive calls) in 71.094 seconds Ordered by: internal time, cumulative time ncalls tottime percall cumtime percall filename:lineno(function) 5144576 68.331 0.000 68.331 0.000 statcounter.py:44(merge) 20 2.735 0.137 71.071 3.554 statcounter.py:33(__init__) 20 0.017 0.001 0.017 0.001 {cPickle.dumps} 1024 0.003 0.000 0.003 0.000 t.py:16(<lambda>) 20 0.001 0.000 0.001 0.000 {reduce} 21 0.001 0.000 0.001 0.000 {cPickle.loads} 20 0.001 0.000 0.001 0.000 copy_reg.py:95(_slotnames) 41 0.001 0.000 0.001 0.000 serializers.py:461(read_int) 40 0.001 0.000 0.002 0.000 serializers.py:179(_batched) 62 0.000 0.000 0.000 0.000 {method 'read' of 'file' objects} 20 0.000 0.000 71.072 3.554 rdd.py:863(<lambda>) 20 0.000 0.000 0.001 0.000 serializers.py:198(load_stream) 40/20 0.000 0.000 71.072 3.554 rdd.py:2093(pipeline_func) 41 0.000 0.000 0.002 0.000 serializers.py:130(load_stream) 40 0.000 0.000 71.072 1.777 rdd.py:304(func) 20 0.000 0.000 71.094 3.555 worker.py:82(process) ``` Also, use can show profile result manually by `sc.show_profiles()` or dump it into disk by `sc.dump_profiles(path)`, such as ```python >>> sc._conf.set("spark.python.profile", "true") >>> rdd = sc.parallelize(range(100)).map(str) >>> rdd.count() 100 >>> sc.show_profiles() ============================================================ Profile of RDD<id=1> ============================================================ 284 function calls (276 primitive calls) in 0.001 seconds Ordered by: internal time, cumulative time ncalls tottime percall cumtime percall filename:lineno(function) 4 0.000 0.000 0.000 0.000 serializers.py:198(load_stream) 4 0.000 0.000 0.000 0.000 {reduce} 12/4 0.000 0.000 0.001 0.000 rdd.py:2092(pipeline_func) 4 0.000 0.000 0.000 0.000 {cPickle.loads} 4 0.000 0.000 0.000 0.000 {cPickle.dumps} 104 0.000 0.000 0.000 0.000 rdd.py:852(<genexpr>) 8 0.000 0.000 0.000 0.000 serializers.py:461(read_int) 12 0.000 0.000 0.000 0.000 rdd.py:303(func) ``` The profiling is disabled by default, can be enabled by "spark.python.profile=true".

Since it looked quite easy, I took the liberty of making a quick PR that just uses `Utils.startServiceOnPort` to fix this. It works locally for me.
