Hudson commented on YARN-568: ----------------------------- Integrated in Hadoop-Yarn-trunk #215 (See [https://builds.apache.org/job/Hadoop-Yarn-trunk/215/]) YARN-568. Followup; remove an unused field added to Allocation (Revision 1484375) Result = FAILURE cdouglas : http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1484375 Files : * /hadoop/common/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/Allocation.java > FairScheduler: support for work-preserving preemption > ------------------------------------------------------ > > Key: YARN-568 > URL: https://issues.apache.org/jira/browse/YARN-568 > Project: Hadoop YARN > Issue Type: Improvement > Components: scheduler > Reporter: Carlo Curino > Assignee: Carlo Curino > Fix For: 2.0.5-beta > > Attachments: YARN-568-1.patch, YARN-568-2.patch, YARN-568-2.patch, > YARN-568.patch, YARN-568.patch > > > In the attached patch, we modified the FairScheduler to substitute its > preemption-by-killling with a work-preserving version of preemption (followed > by killing if the AMs do not respond quickly enough). This should allows to > run preemption checking more often, but kill less often (proper tuning to be > investigated). Depends on YARN-567 and YARN-45, is related to YARN-569. -- This message is automatically generated by JIRA.
