HBase service components should indicate security state

    XMLWordPrintableJSON

Details

    Description

      The HBase service components should indicate security state when queried by Ambari Agent via STATUS_COMMAND. Each component should determine it's state as follows:

      HBASE_MASTER

      Indicators

      • Command JSON
        • config['configurations']['cluster-env']['security_enabled']
          • = “true”
      • Configuration File: params.hbase_conf_dir + ‘/hbase-site.xml’
        • hbase.security.authentication
          • = “kerberos”
          • required
        • hbase.security.authorization
          • = “true”
          • required
        • hbase.master.keytab.file
          • not empty
          • path exists and is readable
          • required
        • hbase.master.kerberos.principal
          • not empty
          • required

      Pseudocode

      if indicators imply security is on and validate
          if kinit(hbase master principal) succeeds
              state = SECURED_KERBEROS
          else
              state = ERROR 
      else
          state = UNSECURED
      

      HBASE_REGIONSERVER

      Indicators

      • Command JSON
        • config['configurations']['cluster-env']['security_enabled']
          • = “true”
      • Configuration File: params.hbase_conf_dir + ‘hbase-site.xml’
        • hbase.security.authentication
          • = “kerberos”
          • required
        • hbase.security.authorization
          • = “true”
          • required
        • hbase.regionserver.keytab.file
          • not empty
          • path exists and is readable
          • required
        • hbase.regionserver.kerberos.principal
          • not empty
          • required

      Pseudocode

      if indicators imply security is on and validate
          if kinit(hbase region server principal) succeeds
              state = SECURED_KERBEROS
          else
              state = ERROR 
      else
          state = UNSECURED
      

      Note: Due to the cost of calling kinit results should be cached for a period of time before retrying. This may be an issue depending on the frequency of the heartbeat timeout.
      Note: kinit calls should specify a temporary cache file which should be destroyed after command is executed - BUG-29477

      Note: There may be additional work related to REST gateway impersonation
