Quanlong Huang commented on IMPALA-4105:
----------------------------------------
Thank [~amosbird]!
It seems supporting multiple partition specs in the same command is a low
haning fruit so we don't need to evaluate the partition predicates in catalogd
side.
{code:sql}
REFRESH tabA
PARTITION (...)
PARTITION (...)
PARTITION (...)
...{code}
Filed IMPALA-14089 as a sub-task for this and uploaded a patch for review:
