[SPARK-4681] Enable executor blacklisting by default.
This commit sets the default value of
spark.scheduler.executorTaskBlacklistTime
to 5 seconds, so that if a task fails on a particular executor, it won't
be re-launched on the same executor until 5 seconds has elapsed, to allow
time for the task to (preferably) be launched on a different executor, where
it may be more likely to complete successfully.
One question here is whether we should now document this configuration
option,
under advanced options?
This enabling is as-per the very old JIRA and the discussion on #8760
@davies let me know whether you think this seems like an appropriate
default?
