Subject [Impala-ASF-CR] IMPALA-6280: Materialize TupleIsNullPredicate for insert sorts
Date Fri, 08 Dec 2017 20:20:33 GMT
Hello Alex Behm, 

I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).

Change subject: IMPALA-6280: Materialize TupleIsNullPredicate for insert sorts

IMPALA-6280: Materialize TupleIsNullPredicate for insert sorts

When a sort is inserted into a plan for an INSERT due to either the
target table being a Kudu table or the use of the 'clustered' hint,
and a TupleIsNullPredicate is present in the output of the sort, the
TupleIsNullPredicate may reference an incorrect tuple (i.e. not the
materialized sort tuple), leading to errors.

The solution is to materialize the TupleIsNullPredicate into the sort
tuple and then perform the appropriate expr substitutions, as is
already done for the case of analytic sorts.

- Added an e2e test with a query that would previously fail.
