Ambari Pig View - fails on permisisons for 'pig.tar.gz/pig/bin/pig'

[#1]

Installed Ambari Pig View, but am not able to run Jobs via the View.

The Pig view was installed on Azure IaaS, Ambari 2.4.1 and the Pig view is a 'Local Cluster' configuration. It errors out without any stdout or stderr information displaying on the Pig view screen (stdout and stderr are available in the job logs). In the job logs Found the following message:

Have not had this error before on previous installs on different clusters.

Background Work Performed for Ambari view setup:

• Pig jobs run fine from the grunt shell and from `pig –f`. No problems there.
• Ensured all Proxyuser/group setup and user hdfs directory work was done according to the instructions on Hortonworks Docs. http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.1.0/bk_ambari-views/content/ch_using_pig_view.ht...
• Confirmed WebHCat server is running.

Additional work performed so far (kindly assisted by Ravi Gangappa):

• Double-checked the proxyusers in Ambari hdfs and hive configs
• Confirmed that this should not be a port issue (opened up all ports in Azure)
• Gave wide-open permissions to HDFS /hdp/apps/2.5.0.0-1245/pig/pig.tar.gz

Thanks in advance for your assistance.

Can you upload the screenshot for the error?

Hi @Sagar Shimpi. I am attaching a screenshot, but the error does not appear in the screenshot. It is in the syslog file for the pig script job. Ravi Gangappa was looking into it this afternoon but we were not able to find the problem yet. screen-shot-2016-11-19-at-103336-pm.png

I will send you via email the text of the HipChat we had.
