Ambari Smoke test for HBase fails

[#1]

SYMPTOM: Ambari smoke test fails for hbase service. Below is the current scenario -

• Ranger is installed in the cluster
• HBase policy has been enabled
• ambari-qa user has the privileges correctly defined in the HBase policy

ERROR:

ERROR: org.apache.hadoop.hbase.security.AccessDeniedException: Insufficient permissions (user=ambari-qa, scope=default, params=[namespace=default,table=default:ambarismoketest,family=family],action=CREATE)

2015-10-27 09:52:03,342 ERROR [main] client.AsyncProcess: Failed to get region location 
org.apache.hadoop.hbase.TableNotFoundException: Table 'ambarismoketest' was not found, got: XXXXX01.

ROOT CAUSE:

If the Ranger co-processor is not correctly defined in the HBase configuration, the smoke test from Ambari would fail. Any table creation as non-hbase user could also fail.

RESOLUTION:

Verify the Ranger configuration for HBase. Ensure that the following properties are set correctly and that the co-processors include Ranger classes

hbase.coprocessor.master.classes
hbase.coprocessor.region.classes
hbase.coprocessor.regionserver.classes

All of the above should include org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor

hbase.security.authorization should be enabled i.e. set to true.
