> {{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}}
