Subject Re: Connecting to HBase with Kerberos
Date Thu, 12 Feb 2015 00:52:12 GMT
Hi Dima,

Thanks for the prompt response.

Here's what we are doing and the error we are seeing:

Code:
System.setProperty("javax.security.auth.useSubjectCredsOnly", "false");
final Configuration hBaseConfig = HBaseConfiguration.create();
hBaseConfig.setInt("timeout", 120000);
hBaseConfig.set("hbase.zookeeper.quorum", "*************");
hBaseConfig.set("hbase.zookeeper.property.clientPort", "2181");
hBaseConfig.set("hadoop.security.authentication", "kerberos");
hBaseConfig.set("hbase.security.authentication", "kerberos");
hBaseConfig.set("hbase.master.kerberos.principal", "*****************");
hBaseConfig.set("hbase.regionserver.kerberos.principal", "*******************");
hBaseConfig.set("hbase.master.keytab.file", "hbase.keytab");
hBaseConfig.set("hbase.regionserver.keytab.file", "hbase.keytab");
UserGroupInformation.setConfiguration(hBaseConfig);

UserGroupInformation ugi = UserGroupInformation.loginUserFromKeytabAndReturnUGI("principle_name",
		"user.keytab");
	
		
		
Error:
