[STORM-733] ShellBolts that don't respond to heartbeats are not being killed

• Type: Bug
• Status: Closed
• Priority: Critical
• Resolution: Abandoned
• Affects Version/s: 0.9.3

Description

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. Heartbeat flow should not assume process had exited.
