[jira] [Commented] (YARN-9049) Add application submit data to state store

    [ https://issues.apache.org/jira/browse/YARN-9049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17360505#comment-17360505 ]

-------------------------------------

Hi, [~botong], [~bibinchundatt]

I have developed a patch which persisted ApplicationSubmissionContext in zk, but I wonder if there will be too much pressure on zk, cause as we know every NM holds a connect to zk. Moreover, query for ApplicationSubmissionContext  queries zk directly, not concerned about the cache.
