HMaster error during startup

HMaster throws error as below during startup

FATAL [ip-:16000.activeMasterManager] master.HMaster: The coprocessor org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor threw java.lang.RuntimeException: /etc/hbase/ (No such file or directory)

This is happening because the ranger co-processor is defined in xml config to load but the requested plugin is not installed. Remove below attributes from hbase-site.xml

  • hbase.coprocessor.master.classes
  • hbase.coprocessor.region.classes
  • hbase.coprocessor.regionserver.classes
Now restart the HMaster process.
