      <!-- markdown -->

      Users of the MOB feature can now use the `mobrefs` utility to get statistics about data in the MOB system and verify the health of backing files on HDFS.

      ```
      HADOOP_CLASSPATH=/etc/hbase/conf:$(hbase mapredcp) yarn jar \
          /some/path/to/hbase-shaded-mapreduce.jar mobrefs mobrefs-report-output some_table foo
      ```

      See javadocs of the class `MobRefReporter` for more details.

      the reference guide has added some information about MOB internals and troubleshooting.
