Carlo Curino created YARN-568: --------------------------------- Summary: 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
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. -- This message is automatically generated by JIRA.
