stack commented on HBASE-17007: ------------------------------- NP. Just thought occassional pain correlating between the two logs rather than one on the rare case of a zk issue small price to pay for some general clean up. Lets see if any other opinions. On sessionids, they will still be in the logs reported by our RecoverableZooKeeper. We can't remove the duplication. ZK spews at INFO level and logs properties and CLASSPATH duplicating our doing emissions of the same. Can't turn it off. Then there are also the occasional complaints from client like below (here it is timing around shutdown): 2016-11-03 12:39:49,832 INFO [M:0;172.21.1.131:61739] zookeeper.MiniZooKeeperCluster: Shutdown MiniZK cluster with all ZK servers 2016-11-03 12:39:49,982 INFO [172.21.1.131:61739.activeMasterManager-SendThread(localhost:2181)] zookeeper.ClientCnxn: Opening socket connection to server localhost/0:0:0:0:0:0:0:1:2181.
