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.
