             Summary: 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


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.
