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.

Matei Zaharia 63da22c025 Update REPL code to use our own version of JLineReader, which fixes #89. 
I'm not entirely sure why this broke in the jump from Scala 2.9.0.1 to
2.9.1 -- maybe something about name resolution changed?
