shameersss1 opened a new pull request, #7722:
URL: https://github.com/apache/hadoop/pull/7722
### Description of PR
Pending MPUs are aborted by default for S3 express store. This leads to job
failure for use cases where the directory needs be purged before the final job
commit, Hence disabling the pending MPUs purging for all types of buckets.
### How was this patch tested?
Test with `us-east-1` with S3 express store bucket. The following tests were
failing with and without the change
```
