Íñigo Goiri commented on HDFS-13704:
------------------------------------
HDFS-6525 currently is defined within HDFS-6382 as supporting HDFS TTL.
However, this could be general and be used in cases like ADLs.
Here, we only need to capture the setXattr in AdlFileSystem and use the proper
ADLS API if the xttar is something like user.expiry or user.ttl.
> Support expiry time in AdlFileSystem

> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Íñigo Goiri
> Assignee: Anbang Hu
> Priority: Major
>
> ADLS supports setting an expiration time for a file.
> We can leverage Xattr in FileSystem to set the expiration time.
> This could use the same xattr as HDFS-6382 and the interface from HDFS-6525.
