Subject [jira] [Updated] (MAPREDUCE-2424) MR-279: counters/UI/etc. for uber-AppMaster (in-cluster LocalJobRunner for MRv2)
Date Fri, 08 Apr 2011 03:32:05 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2424?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Greg Roelofs updated MAPREDUCE-2424:
------------------------------------

    Description: 
Polish uber-AM (MAPREDUCE-2405).  Specifically:
* uber-specific counters ("command-line UI")
* GUI indicators
** RM all-containers level
** multi-job app level [if exists]
** single-job level
* fix uber-decision ("is this a small job?"):
** memory criterion
** input-bytes criterion
* disable speculation
* isUber() method (somewhere) for unit tests to use
* delete (most of) old UberTask code (MAPREDUCE-1220; came in with initial MR-279 branch)
* implement non-RPC, local version of umbilical
* AM restart (default 4 tries) on another node on any task-attempt failure
* uber-specific metrics?
* rename configurables? (still "ubertask"-based)


  was:"Port" MAPREDUCE-1220 to MRv2.  This is an optimization for small jobs wherein all tasks
run on the same node in the same JVM/container.
