Reynold Xin 761ea65a98 Added a test for the previous commit (failing to serialize task results

Ankur Dave ad4ebff42c Deduplicate exceptions when printing them 
The first time they appear, exceptions are printed in full, including
a stack trace. After that, they are printed in abbreviated form. They
are periodically reprinted in full; the reprint interval defaults to 5
seconds and is configurable using the property
spark.logging.exceptionPrintInterval.

Ankur Dave 35b6358a7c Report errors in tasks to the driver via a Mesos status update 
When a task throws an exception, the Spark executor previously just
logged it to a local file on the slave and exited. This commit causes
Spark to also report the exception back to the driver using a Mesos
status update, so the user doesn't have to look through a log file on
the slave.

Here's what the reporting currently looks like:

    # ./run spark.examples.ExceptionHandlingTest master@203.0.113.1:5050
    [...]
    11/10/26 21:04:13 INFO spark.SimpleJob: Lost TID 1 (task 0:1)

Matei Zaharia 9e4c79a4d3 Closure cleaner unit test 2011-11-08 00:40:15 -08:00
Matei Zaharia f346e64637 Updates to the closure cleaner to work better with closures in classes. 
Before, the cleaner attempted to clone $outer objects that were classes
(as opposed to nested closures) and preserve only their used fields,
which was bad because it would miss fields that are accessed indirectly
by methods, and in general it would confuse user code. Now we keep a
reference to those objects without cloning them. This is not perfect
because the user still needs to be careful of what they'll carry along
into closures, but it works better in some cases that seemed confusing
before. We need to improve the documentation on what variables get
passed along with a closure and possibly add some debugging tools for it
as well.

Fixes #71 -- that code now works in the REPL.

Ankur Dave 06637cb69e Fix PairRDDFunctions.groupWith partitioning 
This commit fixes a bug in groupWith that was causing it to destroy
partitioning information. It replaces a call to map with a call to
mapValues, which preserves partitioning.

Matei Zaharia d12122502b Various improvements to Kryo serializer: 
- Replaced modified Kryo version with the standard one augmented with
  the kryo-serializers package, which includes support for classes with

- The kryo-serializers version also fixes issue #72.
- Added a bunch of tests.
- Serialize maps and a few other common types properly by default.

Matei Zaharia c4dd68ae21 Merge branch 'mos-bt' 
This merge keeps only the broadcast work in mos-bt because the structure
of shuffle has changed with the new RDD design. We still need some kind
of parallel shuffle but that will be added later.

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

all) but we can fix that later.

Ankur Dave e30313aa2c Added DiskSpillingCache 
DiskSpillingCache is a BoundedMemoryCache that spills entries to disk
when it runs out of space. Currently the implementation is very
simple. In particular, it's missing the following features:

- Error handling for disk I/O, including checking of disk space levels
- Bringing an entry back into memory after fetching it from disk

In addition, here are some features that aren't critical but should be
implemented soon:

- Spilling based on a user-set priority in addition to LRU
- Caching into a subdirectory of spark.DiskSpillingCache.cacheDir
  rather than the root directory

Mosharaf Chowdhury 0416cc22d2 Picking peers weighted by the number of rare blocks they have. A block is rare if there are at most 2 copies in the neighborhood. Better number can be used (some function of neighborhood size) 2011-02-15 16:27:44 -08:00

Mosharaf Chowdhury 2b946fb2d1 pickBlockRarestFirst and gossips commented OUT for now. 
Problem with the rarestFirst implemention is that we are picking peers randomly first and then picking blocks from the random peer using rarestFirst. NOT the right away to do it. It should be the other way around.
Problem with gossip is that peers might end up overwriting newer information by older ones. To fix that we either have to have timestamps or must match the bitVectors before overwriting.
