> ABFS: [FnsOverBlob] Empty Page Issue on Subsequent ListBlob call
> ----------------------------------------------------------------
>
> Key: HADOOP-19572
> URL: https://issues.apache.org/jira/browse/HADOOP-19572
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.5.0, 3.4.1
> Reporter: Anuj Modi
> Priority: Major
> Labels: pull-request-available
>
> We came across a new behavior from server where ListBlob call can return
> empty list even after returning a next marker(continuation token) from
> previous list call.
> This is to handle that case and do not infer listing to be incomplete.
