stack commented on HBASE-4094:
------------------------------

@Feng Thank you for digging in on this important issue.  As Jieshan asks, are you going to
fix all the issues not already addressed by --fix listed above?  If so, do you think it best
to do it one per issue (if you'd rather piecemeal it) or do you want to make a monster patch
to do them all in this issue?

I looked at your patch and it seems to comment out a line of code and add a comment.

Regards 18 above, when you say collect the regioninfo from regionserver and hdfs, what do
you mean?  What if the region is not on a regionserver?  If its in the filesystem, how will
you find it?  You only have the gap in the table and from here you need to get to the encoded
name of the region in the filesystem.  Are you thinking of looking at all the regions in the
filesystem and getting all of their .regioninfos and then checking for which has a start and
stop key that matches the hole?

If this fails, yes, create a new region to bridge the hole.

Do you think this issue has overlap with HBASE-4058 Feng?

Thanks.
