      Question

      When CTBase accesses the HBase service with the Ranger plug-ins enabled and you are creating a cluster table, a message is displayed indicating that the permission is insufficient.

      ERROR: Create ClusterTable failed. Error: org.apache.hadoop.hbase.security.AccessDeniedException: Insufficient permissions for user 'ctbase2@HADOOP.COM' (action=create)

      Answer

      CTBase users can configure permission policies on the Ranger page and grant the READ, WRITE, CREATE, ADMIN, and EXECUTE permissions to the CTBase metadata table _ctmeta_, cluster table, and index table.
