[jira] [Commented] (HADOOP-17281) Implement
FileSystem.listStatusIterator() in S3AFileSystem
[ https://issues.apache.org/jira/browse/HADOOP-17281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17201034#comment-17201034 ]
Steve Loughran commented on HADOOP-17281:
-----------------------------------------
looking forward to this. Needs a followup across our internal code to make sure that this is used when we list -benefits large HDFS directory listings too. In those situation, I think we should also call close() at the end if they are closeable. We should set an example for all
Once HADOOP-16830 is in, it will be easier to iterate

> Issue Type: Bug
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Mukund Thakur
> Assignee: Mukund Thakur
> Priority: Major
>
> Currently S3AFileSystem only implements listStatus() api which returns an array. Once we implement the listStatusIterator(), clients can benefit from the async listing done recently
