    Description

      I've reproduced this problem consistently on a 20 node cluster.

      The first run fails on a node (jon-snaphots-2 in this case) to take snapshot due to a NotServingRegionException (this is acceptable)

      Subsequent snapshot attempts that require jon-snapshot-2 to participate fail like this:
