-------------------------------------
Summary: ShellBolts that don't respond to heartbeats are not being
killed
Key: STORM-733
URL: https://issues.apache.org/jira/browse/STORM-733
Project: Apache Storm
Issue Type: Bug
Affects Versions: 0.9.3
Reporter: Re'em Bensimhon
Assignee: Re'em Bensimhon
Priority: Critical
In cases where a multilang bolt is stuck (say, an infinite loop), the
heartbeats are supposed to detect the issue and kill the supervisor process.
In 0.9.3 this doesn't happen due to
backtype.storm.utils.ShellProcess.getErrorsString() call in ShellBolt.die()
This call, which in turn executes IOUtils.toString(processErrorStream) will
block the thread until process exits. Heartbean flow should not assume process
had exited.
