Fixed cache replacement behavior of BlockManager:
...
- Partitions that get dropped to disk will now be loaded back into RAM
after they're accessed again
- Same-RDD rule for cache replacement is now implemented (don't drop
partitions from an RDD to make room for other partitions from itself)
- Items stored as MEMORY_AND_DISK go into memory only first, instead of
being eagerly written out to disk
- MemoryStore.ensureFreeSpace is called within a lock on the writer
thread to prevent race conditions (this can still be optimized to
allow multiple concurrent calls to it but it's a start)
- MemoryStore does not accept blocks larger than its limit

Fixed several bugs that caused weird behavior with files in spark-shell:
...
- SizeEstimator was following through a ClassLoader field of Hadoop
JobConfs, which referenced the whole interpreter, Scala compiler, etc.
Chaos ensued, giving an estimated size in the tens of gigabytes.
- Broadcast variables in local mode were only stored as MEMORY_ONLY and
never made accessible over a server, so they fell out of the cache when
they were deemed too large and couldn't be reloaded.

Log message which records RDD origin
...
This adds tracking to determine the "origin" of an RDD. Origin is defined by
the boundary between the user's code and the spark code, during an RDD's
instantiation. It is meant to help users understand where a Spark RDD is
coming from in their code.
This patch also logs origin data when stages are submitted to the scheduler.
Finally, it adds a new log message to fix an inconsitency in the way that
dependent stages (those missing parents) and independent stages (those
without) are logged during submission.

number of partitions we ask to partition it into. Also, removed a test

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)

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.

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

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)

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.
