Ken Weiner commented on HBASE-4235: ----------------------------------- I am seeing similar behavior after restart of my HBase 0.90.4 cluster. The messages that are printed continuously look like the below. Is it the same issue? Also, ZOOKEEPER-1159 is not yet resolved yet. Which upstream issue was marked as invalid? {noformat} - Socket connection established to localhost/127.0.0.1:2181, initiating session - Unable to read additional data from server sessionid 0x1345e2d625d0009, likely server has closed socket, closing socket connection and attempting reconnect {noformat} > Attempts to reconnect to expired ZooKeeper sessions > --------------------------------------------------- > > Key: HBASE-4235 > URL: https://issues.apache.org/jira/browse/HBASE-4235 > Project: HBase > Issue Type: Task > Affects Versions: 0.92.0, 0.90.5 > Reporter: Andrew Purtell > Assignee: Andrew Purtell > > In a couple of instances of short network outages, we have observed afterward > zombie HBase processes attempting over and over to reconnect to expired > ZooKeeper sessions.
