Hello Quanlong Huang, Anurag Mantripragada, Vihang Karajgaonkar, Impala Public
Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/15371
to look at the new patch set (#2).
Change subject: IMPALA-9429: Unioned partition columns break partition pruning
......................................................................
IMPALA-9429: Unioned partition columns break partition pruning
In the case of a union query where predicates are pushed into the union,
predicate Exprs can contain SlotReft that are transformed into constants
after analysis and eligible for constant folding. During partition
pruning there is a check that eligible constant folding has already
occurred which was failing and reporting IllegalStateException since the
surrounding code only handles specific cases.
This fix adds constant a folding call after union substitutions occur
from SingleNodePlanner.createUnionPlan
Testing:
Testcases added to PlannerTest/union.test based on provided repo using
alltypes tables.
