-------------------------------------
The configuration for Pig View in Kerberized environment is documented in the
following blog:
https://developer.ibm.com/hadoop/2016/08/08/ambari-pig-view-kerberos-enabled-clusters/
No changes in the code was required for the view to get working, only the
configuration had to be performed correctly.

> Key: AMBARI-17102
> URL: https://issues.apache.org/jira/browse/AMBARI-17102
> Project: Ambari
> Issue Type: Bug
> Components: ambari-views, contrib
> Affects Versions: trunk
> Reporter: Keta Patel
> Assignee: Keta Patel

> Steps to reproduce the issue:
> 1. Install a cluster containing Pig and Hive services.
> 2. Create a Pig View Instance following the steps from
> http://docs.hortonworks.com/HDPDocuments/Ambari-2.1.0.0/bk_ambari_views_guide/bk_ambari_views_guide-20150721.pdf
> 3. Go to the Pig View instance and create a new script with some content and
> save it. I have used the following content in my script:
> A = load '/tmp/passwd' using PigStorage(':');
> 4. Kerberize the Cluster from Admin -> Kerberos page
> 5. Kerberize the ambari-server following the link
> https://docs.hortonworks.com/HDPDocuments/Ambari-2.1.2.1/bk_Ambari_Security_Guide/content/_optional_set_up_kerberos_for_ambari_server.html
> 6. Make sure to update the Pig View configuration with the correct Settings
> for "WebHDFS Authentication" and "WebHCat Username". Also ensure that the
> "Cluster Configuration" is "Custom" with the correct values set for "WebHDFS
> FileSystem URI*", "WebHCat Hostname" and "WebHCat Port".
> 7. Go to the Pig View instance and open the script created earlier. Click the
> "Execute" button to run the script.
> 8. The following error shows up:
> java.lang.IllegalArgumentException: Path segment is null
> java.lang.IllegalArgumentException: Path segment is null
