This happens because the async requestMap's key is > "node_name" > I discovered this when [~alabax] shared some logs of a restore issue, where > the second replica got added before the first replica had completed it's > restorecore action. > While looking at the logs I noticed that the overseer never called > REQUESTSTATUS for the restorecore action , almost as if it had missed > tracking that particular async request. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
