Subject Problem with HBase + Kerberos
Date Thu, 20 Aug 2015 12:46:45 GMT
Hi all,

Since I kerberized my cluster, it seems like I can't use HBase anymore ...
For example, executing  create 'toto','titi' on HBase shell results in the
printing of this line endlessly :
WARN  [main] security.UserGroupInformation: Not attempting to re-login
since the last re-login was attempted less than 600 seconds before.

And nothing else happens.
I tried to restart HDFS and HBase, and to re-generate credentials and
keytabs, but nothing changed.
As for the logs, they are not very explicits, as the only thing they say
(and keep saying) is :

2015-08-20 13:50:12,697 DEBUG [RpcServer.reader=2,port=60000]
ipc.RpcServer: Created SASL server with mechanism = GSSAPI

2015-08-20 13:50:12,707 DEBUG [RpcServer.reader=2,port=60000]
ipc.RpcServer: Will send token of size 32 from saslServer.
2015-08-20 13:50:12,708 DEBUG [RpcServer.reader=2,port=60000]
ipc.RpcServer: RpcServer.listener,port=60000: DISCONNECTING client
192.168.6.148:43014 because read count=-1. Number of active connections: 3

Do anyone has an idea about where this might come from, or how to solve it
? Because I couldn't find much documentation about this.
Thanks in advance for your help !
