----------------------------------------

Can we move this to target at 4.1?

>    Affects Versions: Impala 3.3.0

> We kind of assumed that the table's writeId  is increased during allocateWriteId or commit, so we don't have to set it with a separate API call during INSERT. https://gerrit.cloudera.org/#/c/14037/ sets it in some specific cases (if STATS_ACCURATE is set, because in this case we call alter_table/partitions to remove), but it is generally not touched.
> I am not sure that it is Impala's duty to set it, it would be probably better if HMS would do it by itself.
