> 6 node cluster was running randomwalk when the MultiTable module failed. A
> BatchWriter was trying to add a new Mutation to a table in
> {{o.a.a.test.randomwalk.multitable.Write}}. The call to {{addMutations}}
> failed with a MutationsRejectedException with the information that there was
> an exception on the server.
> In actuality, the addition of this mutation triggered a flush and tried to
> ship it over to a tabletserver. The tabletserver hosting the tablet for that
> mutation was under load but still responsive. The hold time was exceeded for
> this tserver, but all the client sees is that there was *some* exception on
> this server.
> If the client actually *knew* that commits were being held, it could
> correctly back off (sleep) and retry the mutations since the last flush.
> Right now, they can't really do anything. Additionally, being unable to get
> the mutations that were buffered since the last flush is sub-par, but that
> can be worked around.
