Todd Lipcon commented on HBASE-4388:
------------------------------------
Any chance we can improve the test coverage for migration? This is a critical
feature that impacts metadata integrity, and doesn't get a lot of "implicit
coverage" from people using it, since most of us test with fresh clusters on
trunk. It concerns me that of the two times I've done an actual migration from
90 to trunk, I've run into nasty bugs.
If this isn't easy to test for, I'll try to add tests in HBASE-4389 as well.
