Oh! these are files in HDFS.
You can delete them through HDFS command line after logging as the hdfs user. Something like su hdfs hdfs dfs -ls /user/ drwxrwx--- - ambari-qa hdfs 0 2017-07-12 03:37 /user/ambari-qa? hdfs dfs -rmr /user/ambari-qa I am not familiar with the usage of File View but looks like creating and logging in as user "hdfs" should work. ________________________________ From: Adaryl Wakefield <[email protected]> Sent: Tuesday, July 11, 2017 9:57 PM To: [email protected] Subject: RE: proper Ambari permissions Actually they aren't even all files. I can't blow away directories either.

In general Ambari runs as root unless configured with a custom user. Some of the files it manages may be created as the service user (say HDFS data directories are owned by HDFS service user). -Sumit ________________________________ From: Adaryl Wakefield <[email protected]<mailto:[email protected]>> Sent: Tuesday, July 11, 2017 8:30 PM To: [email protected]<mailto:[email protected]> Subject: proper Ambari permissions When I'm working in Ambari, sometimes I can't manage files because whatever user I'm working under doesn't have permission. 1. What account does Ambari use when it is interacting with the various other programs? 2. How do I need to set my permissions so that when I'm in Ambari as admin, I'm able to create and blow away things at will?
