Josh Elser created ACCUMULO-4065: ------------------------------------ Summary: Strange temporary errors in Master after upgrade Key: ACCUMULO-4065 URL: https://issues.apache.org/jira/browse/ACCUMULO-4065 Project: Accumulo Issue Type: Bug Components: master Reporter: Josh Elser Assignee: Josh Elser
I'm running into a problem that I saw quite a while back in ACCUMULO-3653 I'm still trying to understand what happened, but what I understand so far is that, Accumulo was running, a newer version was installed beside the running version, Accumulo was stopped, the symlink changed, and the new version was started. After this, we started seeing a number of errors in the Master. Shortly after that, the cluster was restarted and the errors stopped happening. This is what I can extract from the logs: {noformat} 2015-11-19 22:42:47,115 [rpc.TServerUtils] DEBUG: Instantiating default, unsecure custom half-async Thrift server 2015-11-19 22:42:47,122
