[jira] [Created] (HBASE-12739) Avoid too large identifier of
ZooKeeperWatcher
Liu Shaohui created HBASE-12739:
-----------------------------------
Summary: Avoid too large identifier of ZooKeeperWatcher
Key: HBASE-12739
URL: https://issues.apache.org/jira/browse/HBASE-12739
Project: HBase
Issue Type: Bug
Reporter: Liu Shaohui
Assignee: Liu Shaohui
Priority: Minor
For each SyncConnected event, the ZooKeeperWatcher will append the session id to its identity.
During the failover of zk, the zookeeper client can connect to the zk server, but the the zk server can not serve the request, so the client will try continually, which will produce many SyncConnected events and a very large identifier of ZooKeeperWatcher in hbase log.
