Hive table 'myntra_wms.myntra_wms_item' is corrupt. Found sub-directory 'abfs://bifrostx-hive-data@gen2hivebifros.dfs.core.windows.net/prod-data/myntra_wms.db/myntra_wms_item/part_created_on=202105/base_0004042/base_0004042' in bucket directory for partition: part_created_on=202105

Why it happens:
Multiple compaction jobs for the same transactions can be triggered if the HMS gets restarted and the MR job is still in progress.
