Zoltan Haindrich commented on HIVE-18285:
-----------------------------------------
I just thinked about adding a testcase which triggers the path you have just
found that it's broken...
set a preevent listener which changes something....and then show that the
listener is respected by the statstask.
but anyway I'm not against this change: +1
> StatsTask uses a cached ql.metadata.Table object

> this then causes BasicStatsTask.aggregateStats(Hive) to call
> Hive.alterTable() with a stale Table object. (It misses any changes made by
> any MetaStorePreEventListener)
