Receiving this error with HBase Storage Handler in Hive when I run a query in a Kerberized environment. on HBase 1.5
Caused by: org.apache.hadoop.hbase.exceptions.UnknownProtocolException: org.apache.hadoop.hbase.exceptions.UnknownProtocolException:

The important part being:
No registered coprocessor service found for name
AuthenticationService
in regionhbase:meta,,1
I did some reading and learned that AuthenticationService
is provided by TokenProvider coprocessor.
In hbase-site.xml
ensure these options are configured
hadoop.security.authentication
hbase.coprocessor.master.classes
hbase.coprocessor.region.classes
Ensure values are configured as follows:
<property>
<name>hadoop.security.authentication</name>
<value>kerberos</value>
</property>
<property>
<name>hbase.coprocessor.master.classes</name>
<value>org.apache.hadoop.hbase.security.access.AccessController</value>
</property>
<property>
<name>hbase.coprocessor.region.classes</name>
<value>org.apache.hadoop.hbase.security.token.TokenProvider,org.apache.hadoop.hbase.security.access.AccessController</value>
</property>
Note:
In older versions of HBase the settinghbase.coprocessor.regionserver.classes
was used, make sure you are using the correct; hbase.coprocessor.region.classes
