Syed Shameerur Rahman commented on HADOOP-19576:
------------------------------------------------
[~ste...@apache.org] - I understand this was done because to delete a
directory in S3 express directory, All the pending upload needs to be purged.
But this causes problem in insert overwrite type of job with MagicCommitter.
I think we should make directory purge operation "false" by default for all
types of buckets - Any thoughts on this ?

> For S3 express storage, The directory purge operation is enabled by default.

> Due to this, the pending MPU uploads are purged and query fails with
