Matteo Bertozzi commented on HBASE-9458:
----------------------------------------
{quote}How about catching CorruptedSnapshotException from admin.snapshot() call
so that the test doesn't fail?{quote}
Yes, you can add a "snapshot()" method in SnapshotTestingUtil that wraps
admin.snapshot() with a while and a catch CorruptedException but then you don't
have much control on how many times it fails (which should be low) and what is
the cause.
but feel free to do it if you want the tests always passing and you don't
consider this failure something that you want to look at every time.
