Hyukjin Kwon resolved SPARK-13216.
----------------------------------
Resolution: Incomplete
> Spark streaming application not honoring --num-executors in restarting of an
> application from a checkpoint
> ----------------------------------------------------------------------------------------------------------
>
> Key: SPARK-13216
> URL: https://issues.apache.org/jira/browse/SPARK-13216
> Project: Spark
> Issue Type: Bug
> Components: DStreams, Spark Submit
> Affects Versions: 1.5.0
> Reporter: Neelesh Srinivas Salian
> Priority: Minor
> Labels: Streaming, bulk-closed
>
> Scenario to help understand:
> 1) The Spark streaming job with 12 executors was initiated with checkpointing
> enabled.
> 2) In version 1.3, the user was able to append the number of executors to 20
> using --num-executors but was unable to do so in version 1.5.
> In 1.5, the spark application still runs with 13 executors (1 for driver and
> 12 executors).
> There is a need to start from the checkpoint itself and not restart the
> application to avoid the loss of information.
> 3) Checked the code in 1.3 and 1.5, which shows the command
> ''--num-executors" has been deprecated.
> Any thoughts on this? Not sure if anyone hit this one specifically before.
