The KeeperException was logged at INFO level.
You can issue 'hbase zkcli' command to enter zookeeper shell.
Then use 'rmr <path>' to remove unwanted path.
Cheers

No, that is not an error. It's some informational logging that arguably can
be useful for debugging problems but we should probably be emitting this at
DEBUG level. You can ignore it.
In general, messages you should be concerned about are logged at WARN,
ERROR, or FATAL log levels.
