Chris Nauroth updated HADOOP-12774:
-----------------------------------
Hadoop Flags: Reviewed
+1, with removal of the unused import on commit.
This patch is ready, but if we commit it now, then it will cause a conflict for
HADOOP-13560. That's a big patch that is very close to commit, so I'd rather
not force it to rebase. [~ste...@apache.org], if you decide you want to commit
this and then rebase HADOOP-13560, please go ahead. Otherwise, I'll wait until
after HADOOP-13560 gets committed before I commit this one.
> s3a should use UGI.getCurrentUser.getShortname() for username

> Key: HADOOP-12774
> URL: https://issues.apache.org/jira/browse/HADOOP-12774
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.7.2
> Reporter: Steve Loughran
> Assignee: Steve Loughran
>
> S3a users {{System.getProperty("user.name")}} to get the username for the
> homedir. This is wrong, as it doesn't work on a YARN app where the identity
> is set by HADOOP_USER_NAME, or in a doAs clause.
> Obviously, {{UGI.getCurrentUser.getShortname()}} provides that name,
> everywhere.
> This is a simple change in the source, though testing is harder ... probably
> best to try in a doAs
