Edison Tung 42f8847a21 Revert de01b6deaaee1b43321e0aac330f4a98c0ea61c6^..HEAD 2011-12-01 13:43:25 -08:00
Edison Tung de01b6deaa Fixed bug in RDD
Math.min takes 2 args, not 1. This was not committed earlier for some
reason

Matei Zaharia 22b8fcf632 Added fold() and aggregate() operations that reuse an object to
merge results into rather than requiring a new object allocation
for each element merged. Fixes #95.

Edison Tung a3bc012af8 added takeSamples method
takeSamples method takes a specified number of samples from the RDD and
outputs it in an array.

Ismael Juma 0fba22b3d2 Fix issue #65: Change @serializable to extends Serializable in 2.9 branch
Note that we use scala.Serializable introduced in Scala 2.9 instead of
java.io.Serializable. Also, case classes inherit from scala.Serializable by
default.

Matei Zaharia 969644df8e Cleaned up a few issues to do with default parallelism levels. Also
renamed HadoopFileWriter to HadoopWriter (since it's not only for files)
and fixed a bug for lookup().

Tathagata Das 38f2ba99cc Further changes to HadoopFileWriter. Implemented ability to save RDDs as SequenceFiles and ObjectFiles.
1> HadoopFileWriter changed to take class types as constructor parameters (no more generic type)
2> Multiple types of RDD.saveAsHadoopFile() implemented to provide more saving options
3> RDD.saveAsSequenceFile() automatically converts basic types to Writable types before saving as SequenceFile
4> RDD.saveAsObjectFile() serializes objects and saves them to a ObjectFile
5> SparkContext.objectFile() opens the saved ObjectFiles

Tathagata Das b5e6645505 Cleaner reimplementation of HadoopFileWriter. Introduced TaskContext.
1> HadoopFileWriter works correctly with task failures
2> It can also take an user specified JobConf object for configuration settings
3> A Task can now get information like stage ID, split ID, and attempt ID using TaskContext class
4> Minor changes in SparkContext, DAGScheduler and subclasses to allow specification of TaskContext as a parameter
