Subject HBase Security Configuration
Date Tue, 17 Apr 2012 12:08:20 GMT
Hello,
I'm trying to configure secure HBase using following instruction: https://ccp.cloudera.com/display/CDHDOC/HBase+Security+Configuration.
Our cluster uses Kerberos and everything in Hadoop work fine. But when I start HBase following
exception is thrown 

FATAL org.apache.hadoop.hbase.master.HMaster: Unhandled exception. Starting shutdown.
org.apache.hadoop.security.AccessControlException: Authentication is required

I can't find any info about it. I'm using Hbase 0.92 with Hadoop 0.22
