------------------------------------------
Summary: Configs: Enabling Yarn RM HA through Ambari should enable
work preserving RM restart
Key: AMBARI-8591
URL: https://issues.apache.org/jira/browse/AMBARI-8591
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Dmitry Lysnichenko
Assignee: Dmitry Lysnichenko
Fix For: 2.0.0
Ambari deploy's Yarn RM HA and does not enable work preserving restarts. Which
control how many time am can restart are not set accounting for HA cluster.
mapred-site.xml -> mapreduce.am.max-attempts (defaults to 2)
tez-site.xml -> tez.am.max.app.attempts (defaults to 2)
yarn-site.xml -> yarn.resourcemanager.am.max-attempts (defaults to 2)
In gsInstaller we set this all to 20 which might be over kill but i think when
yarn HA is enabled we should set these to a better value. Yarn team should
provide input on what we should set them if HA is on and if they should be
different if WRP is on as well.
