stack commented on HBASE-17323:
-------------------------------
Fails 50% of the time:
https://builds.apache.org/job/HBASE-Find-Flaky-Tests/lastSuccessfulBuild/artifact/dashboard.html
Can repro fail about same rate locally.
Attached patch doesn't fix the issue (though seems to happen less w/ it in
place).
I see this which seems wrong:

.. so [~Apache9] maybe HBASE-17282 Reduce the redundant requests to meta table
fixes this... let me finish my review there.
