Shweta commented on HADOOP-13656:
---------------------------------
Thanks [~smeng] for the review.
1. The new command "-fs" takes a filesystem argument and hence the use of
{code}cf.addOptionWithValue() {code} . Using this helps in better parsing the
arguments in CommandFormat. I have used Count command as a reference for adding
the new option in Delete.
2. Good catch about the white space. Missed that one.
3. I did not notice the whitespace at L:285. Did you mean line break after
L:286?
Posted patch v004.Please review.

> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs
> Affects Versions: 2.7.3
> Reporter: Steve Loughran
> Assignee: Shweta

> you can't pass in a filesystem or object store to {{fs -expunge}; you have to
> change the default fs
> {code}
> hadoop fs -expunge -D fs.defaultFS=s3a://bucket/
> {code}
> If the command took an optional filesystem argument, it'd be better at
> cleaning up object stores. Given that even deleted object store data runs up
> bills, this could be appreciated.
