akashrn5 opened a new pull request #3191: [CARBONDATA-3360]fix NullPointerException in delete and clean files operation URL: https://github.com/apache/carbondata/pull/3191 ### Problem: when delete is failed due to hdfs quota exceeded or disk space is full, then tableUpdateStatus.write will be present in store. So after that if clean files operation is done, we were trying to assign null to primitive type long, which will throw runtime exception, and .write file will not be deleted, since we consider it as invalid file. ### Solution: if `.write` file is present, then we do not fail clean files, we check for max query timeout for `tableUpdateStatus.write` file and then delete these .write files for any clean files operation after that.
