[jira] [Created] (STORM-1224) ShellBolt only increases memory usage when subprocess doesn't send ack / fail

Jungtaek Lim created STORM-1224:
-----------------------------------

             Summary: ShellBolt only increases memory usage when subprocess doesn't send ack / fail
                 Key: STORM-1224
                 URL: https://issues.apache.org/jira/browse/STORM-1224
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-core, storm-multilang
            Reporter: Jungtaek Lim


In order to handle ack / fail easily, ShellBolt stores generated id and tuple to Map, and remove it when subprocess passes ack or fail to that id.

In other word, if users doesn't make subprocess pass ack or fail, _input Map only increases and never decreases. It would make memory issue when each tuple is big or there're a lot of tuples flowing.
