I just wanted to check if I was missing something before filing the JIRA. I think the fix is very straightforward, will post a patch to MAPREDUCE-5717. > CheckpointAMPreemptionPolicy implements preemption in MR AM via checkpointing > ------------------------------------------------------------------------------ > > Key: MAPREDUCE-5196 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5196 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: mr-am, mrv2 > Reporter: Carlo Curino > Assignee: Carlo Curino > Fix For: 3.0.0 > > Attachments: MAPREDUCE-5196.1.patch, MAPREDUCE-5196.2.patch, MAPREDUCE-5196.3.patch, MAPREDUCE-5196.patch, MAPREDUCE-5196.patch > > > This JIRA tracks a checkpoint-based AM preemption policy. The policy handles propagation of the preemption requests received from the RM to the appropriate tasks, and bookeeping of checkpoints. Actual checkpointing of the task state is handled in upcoming JIRAs. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
