Devaraj Das updated HADOOP-2092:
--------------------------------
Fix Version/s: (was: 0.16.0)
0.15.0
Priority: Blocker (was: Major)
Description:
Pipes process does not die, when the java map task dies.
Pipes process does not die even when the cluster is down.
was:
Pipes process does not die, when the java map task dies.
Pipes process does not die even when the cluster is down.
Noticed an instance of this bug on an app whose pipes process ran for two
complete hours after the parent java map task died.
I think we should introduce a ping mechanism, similar to the one we have for
the task -> tasktracker communication, that periodically pings to check whether
the java map/reduce process is up.
> Pipes C++ task does not die even if the Java tasks die
