Matei Zaharia fd1d255821 Stop objectifying various trackers, caches, etc. 2011-05-17 12:41:13 -07:00
Matei Zaharia 4db50e26c7 Fixed unit tests by making them clean up the SparkContext after use and 
thus clean up the various singletons (RDDCache, MapOutputTracker, etc).
This isn't perfect yet (ideally we shouldn't use singleton objects at
all) but we can fix that later.

Ankur Dave 563c5e717c Refactor and add aggregator support 
Refactored out the agg() and comp() methods from Pregel.run.

Defined an implicit conversion to allow applications that don't use
aggregators to avoid including a null argument for the result of the
aggregator in the compute function.

Ankur Dave 1c8ca0ebe1 Add Bagel test suite 
Note: This test suite currently fails for the same reason that the
Spark Core test suite fails: Spark currently seems to have a bug where
any test after the first one fails.

Mosharaf Chowdhury db7a2c4897 Issue #42 fixed. 2011-04-28 14:30:48 -07:00
Ankur Dave a4c04f3f6f Error handling for disk I/O in DiskSpillingCache 
Also renamed the property spark.DiskSpillingCache.cacheDir to spark.diskSpillingCache.cacheDir in order to follow conventions.

Ankur Dave 12ff0d2dc3 Bring an entry back into memory after fetching it from disk 2011-04-27 22:59:05 -07:00
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 60d1121343 Refactoring: daemonThreadFactories have all been moved to the Utils 
object instead of having multiple copies in Broadcast and Shuffle
objects.

Mosharaf Chowdhury 2742de707a Removed some shuffle implementations. Remaining ones all use local files 
to write map outputs.

Mosharaf Chowdhury 5bf3c83b13 BroadcastSuperTracker (right now for BT) is contacted over TCP instead

Need to do the same for others and consolidate all broadcast mechanisms.

Formatting + consolidation.
