HBase client failing to connect to Kerberized HBase

[#1]

Here is the stacktrace:

And this is the relevant part of the client:

Configuration conf = HBaseConfiguration.create(); conf.set("hadoop.security.authentication", "Kerberos"); UserGroupInformation.setConfiguration(conf) def userInfo = UserGroupInformation.loginUserFromKeytabAndReturnUGI("[email protected]", args[0]);

UserGroupInformation.setLoginUser(userInfo)

[#2 · Accepted solution]

Which user did you use to run the code ?

What's the output of the following command ?

klist -kt /etc/security/keytabs/hbase.service.keytab

Normally hbase.service.keytab should be used by user 'hbase'.

Please illustrate your use case in more detail.

Please take a look at

hbase-common/src/main/java/org/apache/hadoop/hbase/AuthUtil.java

[#3]

Thanks for the klist suggestion, Ted. That and mqureshi's comment solved it for me.

@Mike Thomsen

hbas user is usually hbase/[email protected]. I don't see the host part of the principal. Is this how you have setup your hbase principal?

What are the permissions on your /etc/security/keytabs/hbase.service.keytab file?

[#5]

And you were correct! It's on an AWS cluster and part of the problem was that the principle had the internal interface associated with it so even when I added what I thought was the right host, didn't work until I followed Ted's advice to use klist.

Hi,

I am using below principals for hbase kerberos authentication:

hbase.zookeeper.quorum=localhost
hbase.zookeeper.property.clientPort=2181
hadoop.security.authentication=kerberos
hbase.security.authentication=kerberos
hbase.master.kerberos.principal=zookeeper/[email protected]
hbase.regionserver.kerberos.principal=zookeeper/[email protected]
hbase.kerberos.principal=zookeeper/[email protected]
hbase.kerberos.keytab=zkpr.keytab

Now, when i run my spark job on local it is not connecting to hbase, it shows error message:

Unable to connect to zookeeper/[email protected] to zookeeper/[email protected].

I have done kinit zookeeper/[email protected] -k -t zkpr.keytab and it is running fine.

Any help will be appreciated.
