In the process, it adds transitions from NEW to FINAL_SAVING. > This leads to the RM trying to update entries in the state-store that do not > exist. On ZKRMStateStore, this leads to the RM crashing. > Previous description: > ZKRMStateStore fails to handle updates to znodes that don't exist. For > instance, this can happen when an app transitions from NEW to FINAL_SAVING. > In these cases, the store should create the missing znode and handle the > update. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
