Subject [jira] [Updated] (MAPREDUCE-3572) MR AM's dispatcher is blocked by heartbeats to ResourceManager
Date Fri, 16 Dec 2011 01:11:30 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3572?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli updated MAPREDUCE-3572:
-----------------------------------------------

          Component/s: mr-am
          Description: 
All the heartbeat processing is done in {{RMContainerAllocator}} locking the object. The event
processing is also locked on this, causing the dispatcher to be blocked and the rest of the
AM getting stalled.

The event processing should be in a separate thread.
    Affects Version/s: 0.23.0
        Fix Version/s: 0.23.1
