Aaron Davidson 1418d18af4 SPARK-821: Don't cache results when action run locally on driver 
Caching the results of local actions (e.g., rdd.first()) causes the driver to
store entire partitions in its own memory, which may be highly constrained.
This patch simply makes the CacheManager avoid caching the result of all locally-run computations.

Matei Zaharia 53cd50c069 Change build and run instructions to use assemblies 
This commit makes Spark invocation saner by using an assembly JAR to
find all of Spark's dependencies instead of adding all the JARs in
lib_managed. It also packages the examples into an assembly and uses
that as SPARK_EXAMPLES_JAR. Finally, it replaces the old "run" script
with two better-named scripts: "run-examples" for examples, and
"spark-class" for Spark internal classes (e.g. REPL, master, etc). This
is also designed to minimize the confusion people have in trying to use
"run" to run their own classes; it's not meant to do that, but now at
least if they look at it, they can modify run-examples to do a decent
job for them.

As part of this, Bagel's examples are also now properly moved to the
examples package instead of bagel.

 2013-08-18 19:51:07 -07:00
Matei Zaharia 2a4ed10210 Address some review comments: 
- When a resourceOffers() call has multiple offers, force the TaskSets
  to consider them in increasing order of locality levels so that they
  get a chance to launch stuff locally across all offers

- Simplify ClusterScheduler.prioritizeContainers

- Add docs on the new configuration options

Matei Zaharia 222c897128 Comment cleanup (via Kay) and some debug messages 2013-08-18 19:51:07 -07:00
Matei Zaharia 90a04dab8d Initial work towards scheduler refactoring: 
- Replace use of hostPort vs host in Task.preferredLocations with a
  TaskLocation class that contains either an executorId and a host or
  just a host. This is part of a bigger effort to eliminate hostPort
  based data structures and just use executorID, since the hostPort vs
  host stuff is confusing (and not checkable with static typing, leading
  to ugly debug code), and hostPorts are not provided by Mesos.

- Replaced most hostPort-based data structures and fields as above.

- Simplified ClusterTaskSetManager to deal with preferred locations in a
  more concise way and generally be more concise.

- Updated the way ClusterTaskSetManager handles racks: instead of
  enqueueing a task to a separate queue for all the hosts in the rack,
  which would create lots of large queues, have one queue per rack name.

- Removed non-local fallback stuff in ClusterScheduler that tried to
  launch less-local tasks on a node once the local ones were all
  assigned. This change didn't work because many cluster schedulers send
  offers for just one node at a time (even the standalone and YARN ones
  do so as nodes join the cluster one by one). Thus, lots of non-local
  tasks would be assigned even though a node with locality for them
  would be able to receive tasks just a short time later.

- Renamed MapOutputTracker "generations" to "epochs".

Reynold Xin 3886b54933 A few small scheduler / job description changes.

2. Renamed SparkContext.setDescription to setCurrentJobDescription.

3. Throw an exception if the fair scheduler allocation file is invalid.

This avoids akka log messages (like Spray) from falling back to INFO
on the Stdout logger
2. Initialize netty to use SLF4J in LocalSparkContext. This ensures that
stack trace thrown during shutdown is handled by SLF4J instead of stdout

Matei Zaharia 15b00914c5 Some fixes to the launch-java-directly change: 
- Split SPARK_JAVA_OPTS into multiple command-line arguments if it

- Add the Scala JARs to the classpath if they're not in the CLASSPATH
  variable because the ExecutorRunner is launched with "scala" (this can
  happen when using local-cluster URLs in spark-shell)

The old version reused the object within each task, leading to
overwriting of the object when a mutable type is used, which is expected
to be common in fold.

akka messages, where W = the number of workers.

 2013-04-30 07:51:40 -07:00
Patrick Wendell 540be6b154 Modified version of the fix which just removes all per-record tracking. 2013-04-29 11:32:07 -07:00
Patrick Wendell 224fbac061 Spark-742: TaskMetrics should not employ per-record timing. 
This patch does three things:

1. Makes TimedIterator a trait with two implementations (one a no-op)
2. Makes the default behavior to use the no-op implementation
3. Removes DelegateBlockFetchTracker. This is just cleanup, but it seems like
   the triat doesn't really reduce complexity in any way.

In the future we can add other implementations, e.g. ones which perform sampling.

Imran Rashid b7d9e24394 use TaskMetrics to gather all stats; lots of plumbing to get it all the way back to driver 2013-02-10 14:18:52 -08:00
Stephen Haberman 680f42e6cd Change defaultPartitioner to use upstream split size. 
Previously it used the SparkContext.defaultParallelism, which occassionally
ended up being a very bad guess. Looking at upstream RDDs seems to make
better use of the context.

Also sorted the upstream RDDs by partition size first, as if we have
a hugely-partitioned RDD and tiny-partitioned RDD, it is unlikely
we want the resulting RDD to be tiny-partitioned.

 2013-01-29 10:41:42 -08:00
Matei Zaharia 64ba6a8c2c Simplify checkpointing code and RDD class a little: 
- RDD's getDependencies and getSplits methods are now guaranteed to be
  called only once, so subclasses can safely do computation in there
  without worrying about caching the results.

- The management of a "splits_" variable that is cleared out when we
  checkpoint an RDD is now done in the RDD class.

- A few of the RDD subclasses are simpler.

- CheckpointRDD's compute() method no longer assumes that it is given a
  CheckpointRDDSplit -- it can work just as well on a split from the
  original RDD, because it only looks at its index. This is important
  because things like UnionRDD and ZippedRDD remember the parent's
  splits as part of their own and wouldn't work on checkpointed parents.

- RDD.iterator can now reuse cached data if an RDD is computed before it
  is checkpointed. It seems like it wouldn't do this before (it always
  called iterator() on the CheckpointRDD, which read from HDFS).

Tathagata Das 34e569f40e Added 'synchronized' to RDD serialization to ensure checkpoint-related changes are reflected atomically in the task closure.

Josh Rosen 33cd3a0c12 Remove map-side combining from ShuffleMapTask. 
This separation of concerns simplifies the 
ShuffleDependency and ShuffledRDD interfaces.

Map-side combining can be performed in a
mapPartitions() call prior to shuffling the RDD.

I don't anticipate this having much of a 
performance impact: in both approaches, each tuple
is hashed twice: once in the bucket partitioning
and once in the combiner's hashtable.  The same
steps are being performed, but in a different
order and through one extra Iterator.

Josh Rosen 10bcd217d2 Remove mapSideCombine field from Aggregator. 
Instead, the presence or absense of a ShuffleDependency's aggregator
will control whether map-side combining is performed.
