Subject [jira] Updated: (HADOOP-2092) Pipes C++ task does not die even if the Java tasks die
Date Tue, 23 Oct 2007 10:48:50 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-2092?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
