> {{msck.repair.batch.size}} default to 0 which means msck will try to add all the partitions in one API call to HMS. This can potentially add huge memory pressure on HMS. The default value should be changed to a reasonable number so that in case of large number of partitions we can batch the addition of partitions. Same goes for {{msck.repair.batch.max.retries}}
