             Summary: ShellSpout should send heartbeat tuple while nextTuple() is not called
                 Key: STORM-1928
                 URL: https://issues.apache.org/jira/browse/STORM-1928
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-multilang
            Reporter: Jungtaek Lim
            Assignee: Jungtaek Lim
            Priority: Critical


It affects Storm releases which are greater than 0.9.3 so I didn't set affect version/s. All version lines are affected.

When nextTuple is not calling at any chances (max spout pending, backpressure introduced at 1.0.0, and so on) multi-lang spout don't receive any message from ShellSpout, thus no messages from multi-lang spout side. (because multilang spout and ShellSpout communicates like ping-pong, unlike multilang bolt and ShellBolt)
In result, no heartbeat is being marked, and finally raises subprocess heartbeat timeout.
