[jira] [Created] (HDFS-15628) https throws NPE if a file is a
symlink
Ahmed Hussein created HDFS-15628:
------------------------------------
Summary: 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
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.
