Matei Zaharia ccb67ff2ca Merge pull request #425 from stephenh/toDebugString 
Add RDD.toDebugString.
 2013-01-29 10:44:18 -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 8a25d530ed Optimized checkpoint writing by reusing FileSystem object. Fixed bug in updating of checkpoint data in DStream where the checkpointed RDDs, upon recovery, were not recognized as checkpointed RDDs and therefore deleted from HDFS.

Tathagata Das 34e569f40e Added 'synchronized' to RDD serialization to ensure checkpoint-related changes are reflected atomically in the task closure. Added to tests to ensure that jobs running on an RDD on which checkpointing is in progress does hurt the result of the job. 2012-10-31 00:56:40 -07:00

Tathagata Das ac12abc17f Modified RDD API to make dependencies a var (therefore can be changed to checkpointed hadoop rdd) and othere references to parent RDDs either through dependencies or through a weak reference (to allow finalizing when dependencies do not refer to it any more). 2012-10-29 11:55:27 -07:00
