> I came off a support case (0.98.0) where main zk thread was seen doing the
> following:
> {code}
> at
> org.apache.hadoop.hbase.security.access.ZKPermissionWatcher.refreshAuthManager(ZKPermissionWatcher.java:152)
> at
> org.apache.hadoop.hbase.security.access.ZKPermissionWatcher.refreshNodes(ZKPermissionWatcher.java:135)
> at
> org.apache.hadoop.hbase.security.access.ZKPermissionWatcher.nodeChildrenChanged(ZKPermissionWatcher.java:121)
> at
> org.apache.hadoop.hbase.zookeeper.ZooKeeperWatcher.process(ZooKeeperWatcher.java:348)
> at
> org.apache.zookeeper.ClientCnxn$EventThread.processEvent(ClientCnxn.java:519)
> at org.apache.zookeeper.ClientCnxn$EventThread.run(ClientCnxn.java:495)
> {code}
> There were 62000 nodes under /acl due to lack of fix from HBASE-12635,
> leading to slowness in table creation because zk notification for region
> offline was blocked by the above.
> The attached patch separates refreshNodes() call into its own thread.
> Thanks to Enis and Devaraj for offline discussion.
