Vinod Kumar Vavilapalli commented on YARN-2005: ----------------------------------------------- -1 for backporting this, while I understand that the original feature-ask is useful for avoiding AM scheduling getting blocked, there are far too many issues with the feature as it is. Please see my comments on YARN-4576 and YARN-4837. > Blacklisting support for scheduling AMs > --------------------------------------- > > Key: YARN-2005 > URL: https://issues.apache.org/jira/browse/YARN-2005 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Affects Versions: 0.23.10, 2.4.0 > Reporter: Jason Lowe > Assignee: Anubhav Dhoot > Fix For: 2.8.0 > > Attachments: YARN-2005.001.patch, YARN-2005.002.patch, > YARN-2005.003.patch, YARN-2005.004.patch, YARN-2005.005.patch, > YARN-2005.006.patch, YARN-2005.006.patch, YARN-2005.007.patch, > YARN-2005.008.patch, YARN-2005.009.patch > > > It would be nice if the RM supported blacklisting a node for an AM launch > after the same node fails a configurable number of AM attempts. This would > be similar to the blacklisting support for scheduling task attempts in the > MapReduce AM but for scheduling AM attempts on the RM side. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
