---------------------------------------------------------
This is still present in master. I was looking into the same issue, basically
my understanding is that the loadTable in Hive.java :
[Hive.java#L2630|https://github.com/apache/hive/blob/a4b087b18bd5b0b4023bced68c85cf1e16301fed/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L2630]
calls alterTable even when there is a stats change, and only change happening
is transient_lastDdl because actual alter of stats happens in the next
alter_table event that follows this.
I wanted to change the code in the following way :
{code:java}
if (hasFollowingStatsTask) {
environmentContext = new EnvironmentContext();
environmentContext.putToProperties(StatsSetupConst.DO_NOT_UPDATE_STATS,
StatsSetupConst.TRUE);
}
else {
alterTable(tbl, false, environmentContext, true);
}
{code}
Change above is adding alterTable in else part, ie. when there is no stat task
to follow. But I do not know if loadTable is used in a different code path
where this alterTable is useful irrespective of stat change.
+ [~sershe] [~vihangk1] [~akolb] [~pvary] What do you think about this, can you
think of any case where the alterTable should not be in the else part.
