Change subject: KUDU-3518: Fix the unexpected scan predicate ...................................................................... KUDU-3518: Fix the unexpected scan predicate With the changes introduced in a previous patch[1], there have been reports of errors during scan operations. This patch fixes these scan errors. This patch removes NON-NULL predicates on primary columns implicitly added by ScanSpec::LiftPrimaryKeyBounds(), calling ScanSpec::OptimizeScan() while optimizing InList scan predicates at the DRS level. That's similar to what's done be optimizing the InList predicates based on tablet PK bounds at a higher level. The issue has been investigated and fixed in collaboration with Alexey Serbin. There will be follow-up patches to include tests of this failure.
