Vladimir Rodionov commented on HBASE-12657:
-------------------------------------------

Fixed one failing unit test in a second patch. Run small/medium.long tests. All pass except
TestImportExport, but its fail w/o patch as well. I do not know how to run replication tests.
Please advise.

> We are seeing this behavior when creating indexes in one of our environment.
> When an index is being created, most of the "requests" go into a single region.  The
amount of time to create an index seems to take longer than usual and it can take days for
the regions to compact and split after the index is created.
