> ABFS: [FnsOverBlob] Listing Optimizations to avoid multiple iteration over

> Key: HADOOP-19474
> URL: https://issues.apache.org/jira/browse/HADOOP-19474
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.5.0, 3.4.1
> Reporter: Anuj Modi
> Assignee: Anuj Modi
> Priority: Major
> Labels: pull-request-available
>
> On blob endpoint, there are a couple of handling that is needed to be done on
> client side.
> This involves:
> # Parsing of xml response and converting them to VersionedFileStatus list
> # Removing duplicate entries for non-empty explicit directories coming due
> to presence of the marker files
> # Trigerring Rename recovery on the previously failed rename indicated by
> the presence of pending json file.
> Currently all three are done in a separate iteration over whole list. This is
> to pbring all those things to a common place so that single iteration over
> list reposne can handle all three.
