Subject [jira] [Created] (SOLR-11269) Node gone after reconnecting to ZK
Date Mon, 21 Aug 2017 07:46:02 GMT
Cao Manh Dat created SOLR-11269:

             Summary: Node gone after reconnecting to ZK
                 Key: SOLR-11269
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Cao Manh Dat
            Assignee: Cao Manh Dat

I have seen some failures, related to {{ZkController.OnReconnect}} that made the node "gone"
( it is not present in "/live_nodes" ). In fact any exception during {{OnReconnect.command()}}
execution will made the node "gone". Some of them are
- {{ZkController.createEphemeralLiveNode()}} can throw NodeExistsException
- {{OutOfMemoryError : unable to create new native Thread}} during adding core to {{executorService}}
for recovering
