Indhumathi27 opened a new pull request #3310: Fix DataLoading to MV table when Yarn-Application is killed
URL:
https://github.com/apache/carbondata/pull/3310
Problem:
When dataLoad is triggered on datamaptable and new LoadMetaDetail with SegmentStatus as "InsertInProgress" and segmentMappingInfo is created and then yarn-application is killed. Then on next load, stale loadMetadetail is still in InsertInProgress state and mainTableSegemnts mapped to that loadMetaDetail is not considered for nextLoad resulted in dataMismatch between main table and datamap table
Solution:
Clean up the old invalid segment before creating a new entry for new Load.
