--------------------------------------
Hi [~jmhsieh], [~anoopsamjohn], [~ram_krish].
This patch is used to check the corrupt mob files.
And next we need a tool to check the integrity of mob cells. I think Jon's idea
is very good. Read the hfile and check whether its mob file is present.
If the mob file is not there, how should we do? Add a delete marker for this
ref cell from table client? Or alternatively, could we do some improvement in
scanner?
Now if the mob file is not present or the mob file is corrupt, a cell with a
null value is returned. Could we just filter these cells and read more in
scanner? In this way, the dangling ref cells are not visible, and these
dangling ref cells can be deleted when they are expired.
Please advise. Thanks!

> Now in HFileCorruptionChecker, it only checks the files in regions. We need
> check the mob files too if there are mob-enabled columns in that table.
