[~aash]

According my scenario and [https://github.com/palantir/spark/pull/94] code

task 678.0
outputCommitCoordinator.canCommit will match CommitState(NO_AUTHORIZED_COMMITTER, _, Uncommitted)
=>  CommitState(attemptNumber, System.nanoTime(), MidCommit)

outputCommitCoordinator.commitDone match CommitState(existingCommitter, startTime, MidCommit)
if attemptNumber == existingCommitter =>
 CommitState(attemptNumber, startTime, Committed)

task 678.1
outputCommitCoordinator.canCommit match CommitState(existingCommitter, _, Committed) 

If executor is preempted after outputCommitCoordinator.commitDone, driver still enter into
task deadloop

then driver enter into task deadloop

> Executor sends *AskPermissionToCommitOutput* to driver failed, and retry another sending.
Driver receives 2 AskPermissionToCommitOutput messages and handles them. But executor ignores
the first response(true) and receives the second response(false). The TaskAttemptNumber for
this partition in authorizedCommittersByStage is locked forever. Driver enters into infinite
loop.
