Hello all, I am trying out adding a python bolt in my topology, but it keeps crashing quite frequently. Before adding this python bolt, my topology was EXTREMELY stable and would run for months without any issues. However, after adding the python bolt, the following exception happens quite frequently:
2017-02-23 15:14:04.080 o.a.s.t.ShellBolt [ERROR] Halting process: ShellBolt died. Command: [python, PyBolt.py], ProcessInfo pid:31162, name:PythonBolt exitCode:-1, errorString: java.lang.RuntimeException: subprocess heartbeat timeout at org.apache.storm.task.ShellBolt$BoltHeartbeatTimerTask.run(ShellBolt.java:322) [storm-core-1.0.2.jar:1.0.2] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [?:1.8.0_121] at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) [?:1.8.0_121] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) [?:1.8.0_121] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) [?:1.8.0_121] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [?:1.8.0_121] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [?:1.8.0_121] at java.lang.Thread.run(Thread.java:745) [?:1.8.0_121] 2017-02-23 15:14:04.092 o.a.s.d.executor [ERROR] I am using storm 1.0.2. Any tips or ideas? Thanks
