Is there a way we can refresh multiple partitions in a single statement?.
What I am trying to execute is something like "refresh partition ( col in ('val1','val2',val3'......))".
So that I do not have to fire multiple refresh queries. If it is not present, are there plans to bring this feature anytime in the near future?.

We looked at adding this a while back but ran into some technical issues around whether it should discover new partitions that would match the predicates: https://issues.apache.org/jira/browse/IMPALA-4105
We have a few people actively working on REFRESH/INVALIDATE and related issues, hoping to drastically improve the experience there.

I would like this too. My use case is new data files written to existing partitions, so I'm not concerned with partition discovery.
REFRESH tabA PARTITION (...) PARTITION (...) PARTITION (...)
will be useful
