> ABFS: [FnsOverBlob] Remove Duplicates from Blob Endpoint Listing Across
> Iterations

> Key: HADOOP-19543

> Project: Hadoop Common
> Issue Type: Sub-task

> On FNS-Blob, List Blobs API is known to return duplicate entries for the
> non-empty explicit directories. One entry corresponds to the directory itself
> and another entry corresponding to the marker blob that driver internally
> creates and maintains to mark that path as a directory. We already know about
> this behaviour and it was handled to remove such duplicate entries from the
> set of entries that were returned as part current list iterations.
> Due to possible partition split if such duplicate entries happen to be
> returned in separate iteration, there is no handling on this and caller might
> get back the result with duplicate entries as happening in this case. The
> logic to remove duplicate was designed before the realization of partition
> split came.
> This PR fixes this bug
