Steve Loughran updated HADOOP-18752:
------------------------------------
Release Note: The s3a connector no longer deletes directory markers by
default, which speeds up write operations, reduces iO throttling and saves
money. this can cause problems with older hadoop releases trying to write to
the same bucket. (Hadoop 3.3.0; Hadoop 3.2.x before 3.2.2, and all previous
releases). Set "fs.s3a.directory.marker.retention" to "delete" for backwards
compatibility (was: The s3a connector no longer deletes directory markers by
default; this can cause problems with older hadoop releases trying to write to
the same bucket. Set fs.s3a.directory.marker.retention to delete for backwards

> Change fs.s3a.directory.marker.retention to "keep"
