-----------------------------------
Summary: Pig view fails when execute/explain/syntax check in
kerberos environment
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
