Hi,

 

after disabling Kerberos the HBase Master won't start because no access to zookeeper znode /hbase/shutdown. I tried to remove it in zookeeper shell (started as user root), but no success =>

 

[zk: localhost:2181(CONNECTED) 3] rmr /hbase/shutdown
Authentication is not valid : /hbase/shutdown
[zk: localhost:2181(CONNECTED) 4] getAcl /hbase/shutdown
'sasl,'hbase
: cdrwa
[zk: localhost:2181(CONNECTED) 5]

 

 

How can I forcibly deltete that subtree to be able to start HBase afterwards?

 

Error in HBase Master log:

 

2014-03-31 10:23:41,760 WARN org.apache.hadoop.hbase.zookeeper.ZKUtil: master:60000-0x4451714a72b004b Unable to get data of znode /hbase/shutdown
org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /hbase/shutdown

 

thanks in advance...Gerd...
