Todd Lipcon commented on KUDU-1899:
-----------------------------------
Based on the results of my test, it appears that you can safely just remove
that assertion on diskrowset.cc:216 and everything should be fine. The fix
should be in Kudu 1.3 but in the meantime recompiling your own build from 1.2
with this fix is probably the quickest way to recovery.
