> https throws NPE if a file is a symlink

> Key: HDFS-15628
> URL: https://issues.apache.org/jira/browse/HDFS-15628
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: fs, httpfs
> Reporter: Ahmed Hussein
> Assignee: Ahmed Hussein
> Priority: Major
> Attachments: HDFS-15628.001.patch
>
>
> If a directory containing a symlink is listed, the client (WebHfdsFileSystem)
> blows up with a NPE. If {{type}} is {{SYMLINK}}, there must be {{symlink}}
> field whose value is the link target string. HttpFS returns a response
> without {{symlink}} filed. {{WebHfdsFileSystem}} assumes it is there for a
> symlink and blindly tries to parse it, causing NPE.
> This is not an issue if the destination cluster does not have symlinks
> enabled.
