Force pseudo-tty allocation in spark-ec2 script.

ssh commands need the -t argument repeated twice if there is no local
tty, e.g. if the process running spark-ec2 uses nohup and the parent
process exits.
Merge pull request #271 from ewencp/really-force-ssh-pseudo-tty-0.8

Force pseudo-tty allocation in spark-ec2 script.

ssh commands need the -t argument repeated twice if there is no local
tty, e.g. if the process running spark-ec2 uses nohup and the parent
process exits.

Without this change, if you run the script this way (e.g. using nohup from a cron job), it will fail setting up the nodes because some of the ssh commands complain about missing ttys and then fail.

(This version is for the 0.8 branch. I've filed a separate request for master since changes to the script caused the patches to be different.)
Merge pull request #273 from rxin/top

Fixed a performance problem in RDD.top and BoundedPriorityQueue

BoundedPriority was actually traversing the entire queue to calculate the size, resulting in bad performance in insertion.

This should also cherry pick cleanly into branch-0.8.

Handle IndirectTaskResults in LocalScheduler

This fixes a bug where large results aren't correctly handled when running in local mode.  Not doing this in master because expecting the Local/Cluster scheduler consolidation to go into 0.9, which will fix this issue (see #127)
Merge pull request #320 from kayousterhout/erroneous_failed_msg

Remove erroneous FAILED state for killed tasks.

Currently, when tasks are killed, the Executor first sends a
status update for the task with a "KILLED" state, and then
sends a second status update with a "FAILED" state saying that
the task failed due to an exception. The second FAILED state is
misleading/unncessary, and occurs due to a NonLocalReturnControl
Exception that gets thrown due to the way we kill tasks. This
commit eliminates that problem.

I'm not at all sure that this is the best way to fix this problem,
so alternate suggestions welcome. @rxin guessing you're the right
person to look at this.

Merge pull request #496 from pwendell/master

Fix bug in worker clean-up in UI

Introduced in d5a96fec (/cc @aarondav).

This should be picked into 0.8 and 0.9 as well. The bug causes old (zombie) workers on a node to not disappear immediately from the UI when a new one registers.
