[jira] [Updated] (YARN-11924) Add zkManager.exists(path) check to ZKConfigurationStore:getZkData() and retry mechanism
[ https://issues.apache.org/jira/browse/YARN-11924?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ferenc Erdelyi updated YARN-11924:
----------------------------------
Description:
Should a 'yarn resourcemanager -format-state-store' command is issued while one of the RM is in the INIT state, there is a time period when the /confstore/CONF_STORE path does not exist (because of YARN-11551), on a different occasion, the confstore is being written and the getZkData method returns a null value causing the RM to fail.
To prevent this, added a re-try mechanism before giving up.
