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.
