Josh Rosen 49be084ed3 Use File.pathSeparator instead of hardcoding ':'. 2013-07-29 22:08:57 -07:00
Josh Rosen b95732632b Do not inherit master's PYTHONPATH on workers. 
This fixes SPARK-832, an issue where PySpark
would not work when the master and workers used
different SPARK_HOME paths.

This change may potentially break code that relied
on the master's PYTHONPATH being used on workers.
To have custom PYTHONPATH additions used on the
workers, users should set a custom PYTHONPATH in
spark-env.sh rather than setting it in the shell.

This is useful for when you want just 1 output file (part-00000) but
still up the upstream RDD to be computed in parallel.

Stephen Haberman 6cd68c31cb Update default.parallelism docs, have StandaloneSchedulerBackend use it. 
Only brand new RDDs (e.g. parallelize and makeRDD) now use default
parallelism, everything else uses their largest parent's partitioner
or partition size.

Josh Rosen e9fb25426e Remove hack workaround for SPARK-668. 
Renaming the type paramters solves this problem (see SPARK-694).

I tried this fix earlier, but it didn't work because I didn't run
`sbt/sbt clean` first.

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).
