Description

Not seen in the wild, but inferred from a code review

mkdirs creates an empty dir marker -but it looks for one first

proposed

• only look for file marker and LIST; don't worry about an empty dir marker
• always PUT one there

Saves a HEAD on every mkdir too

Issue Links

• is duplicated by: HADOOP-16879 s3a mkdirs() to not check dest for a dir marker
• relates to: HADOOP-13230 S3A to optionally retain directory markers
