Server Error when downloading files

[#1]

We are having an issue previewing and downloading files from File View.

I noticed one other user on here had a similar problem and their solutions did not work for us.

When attempting to preview a file in file view, it is blank and we get an error in the logs:

02 Mar 2017 16:21:57,867 ERROR [ambari-client-thread-8502] [FILES 1.0.0 AUTO_FILES_INSTANCE] FilePreviewService:96 - Error occurred while previewing /topics/xyz/2017/02/15/xyz.1487116808176.log :

And when we attempt to download a file, it states:

{
  "status": 500,
  "message": "Server Error"
}

If anyone has any insight or have had this problem, please assist. Thank you.

We have also tried creating another Files-View instance and the same error occurs.

@Eric Lloyd

Have you added the "proxyuser" configuration properly in the advanced core-site via Ambari?

hadoop.proxyuser.root.groups=*
hadoop.proxyuser.root.hosts=*

Like:http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.18/bk_ambari-views/content/_configuring_your_cluster_for_files_view.html

- Also what is the size of the file that you are trying to download/view? Is it too large?

That worked! Thank you!!
