GitHub user sandhyasun opened a pull request:
https://github.com/apache/incubator-trafodion/pull/959
Fix for intermittent regression failure executor/TEST015 related to
[TRAFODION-1562]
Caused because preCondition expression was…not being generated for the
code path with the new efficient tree. This caused deletes and inserts to
compete and cause inconsistencies in the index depending on timing. Fix is to
ensure the delete precondition is set for efficient upserts just like it is for
updates and mergeUpdates.
Fixed known diff file for seabase/TEST025
