Description

STR:

1. Was deployed cluster with HDFS, MapReduce2, YARN, Tez, Pig, ZooKeeper, Ambari Metrics, Knox, Ranger via blueprint.
2. Was enabled plugin for HDFS.
3. Go to add service wizard.
4. Choose HBase to install.
5. Go to customize services step. Following properties are noticed with the values as stated:
   hbase.coprocessor.regionserver.classes = deleted
   hbase.coprocessor.master.classes = ""
   hbase.coprocessor.region.classes = "org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint"
6. On "Ranger Plugin" panel of Ranger service enable plugin for HBase. Following properties are noticed with the values as stated:
   hbase.coprocessor.regionserver.classes = "org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor"
   hbase.coprocessor.master.classes" = "org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor"
   hbase.coprocessor.region.classes" = "org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint,org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor"
7. Disable plugin for HBase. Recommendation popup shows following properties with the values stated:

Property	Current value	Recommended value
hbase.coprocessor.regionserver.classes	org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor	org.apache.hadoop.hbase.security.access.AccessController
hbase.coprocessor.master.classes		org.apache.hadoop.hbase.security.access.AccessController
hbase.coprocessor.region.classes	org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint	org.apache.hadoop.hbase.security.access.AccessController,org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint

Expected behavior:

Property	Current value	Recommended value
hbase.coprocessor.regionserver.classes	deleted(absent)	org.apache.hadoop.hbase.security.access.AccessController
hbase.coprocessor.master.classes		org.apache.hadoop.hbase.security.access.AccessController
hbase.coprocessor.region.classes	org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint	org.apache.hadoop.hbase.security.access.AccessController,org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint
