> Better to have multilang subprocess timeout, not relying on supervisor worker
> timeout
> -------------------------------------------------------------------------------------
>
> Key: STORM-1341
> URL: https://issues.apache.org/jira/browse/STORM-1341
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-multilang
> Reporter: Jungtaek Lim
> Priority: Minor
> Fix For: 0.11.0
>
>
> Currently, ShellBolt determines that subprocess is hang if there're no
> message from subprocess within SUPERVISOR_WORKER_TIMEOUT_SECS.
> Since ShellBolt treats all kinds of message to heartbeat (STORM-742), we get
> rid of heartbeat issue that heartbeat tuple cannot processed in time because
> too many other BoltMsgs waiting.
> But it doesn't cover two scenario,
> - STORM-758: Subprocess doesn't send anything - emit, ack, fail - so
> ShellBolt has to rely on heartbeat tuple. It is valid for non-ACK mode.
> - Each (or some kind of) tuple takes very long time to process. For now it
> should be shorter than SUPERVISOR_WORKER_TIMEOUT_SECS.
> It could be better to have multilang subprocess timeout for clarity.
