Description

The Storm ShellBolt is aware of a need_task_ids field in messages received from non-JVM bolts (https://github.com/apache/incubator-storm/blob/master/storm-core/src/jvm/backtype/storm/task/ShellBolt.java :line 233).

This flag determines whether a ShellBolt will in fact respond with task IDs to a request from a non-JVM bolt. No mention of this flag is made in the Storm multilang protocol.

I believe this flag should be added the the multilang protocol description or removed from its implementation.n Personally, I'm not a great fan of how this functionality has been implemented (on a per message basis).
