various classes not supporting a graceful stop() yet.

Reynold Xin d0c6e9f639 Made some RDD dependencies transient to reduce the amount of data needed 
to be serialized in closure serialization. This can significantly reduce
the task setup time in Shark when the query involves a large number of
(Hive) partitions.
 2012-05-16 14:16:55 -07:00
Reynold Xin 16461e2eda Updated Cache's put method to use a case class for response. Previously 
it was pretty ugly that put() should return -1 for failures.
 2012-05-15 00:31:52 -07:00
Reynold Xin 019e48833f Added the capacity to report cache usage status back to the cache 
trackor. This is essential for building a dashboard to see the status of
caches on all slaves.
 2012-05-14 18:39:04 -07:00
Matei Zaharia f48742683a Made caches dataset-aware so that they won't cyclically evict partitions 
from the same dataset.

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.

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 cf81da9485 Optimization: Master sends out at least one copy of each block first regardless of whatever a client is asking for. Once one copy of each block is out, Master then responds to specific blocks from individual receivers. 2011-02-14 15:08:33 -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.
 2011-02-13 13:53:15 -08:00
Mosharaf Chowdhury ca2895ebb0 Fix in rarestFirst implemenation. 
If there are more than one rarest blocks, pick randomly between them (was deterministic before)
