[jira] [Commented] (AMBARI-15387) Pxf service status is currently red

["Andrew Onischuk (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-15387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15191184#comment-15191184 ] 

Andrew Onischuk commented on AMBARI-15387:
------------------------------------------

In status_command we do not add not_managed_hdfs_path_list to hostLevelParams. 
In many services we have separated status_params.py and params.py. During status check only status_params.py is imported.
We can do the same for PXF.

The patch attached fixes the issue.
I am not sure how to test the pxf service that's why assigning this to you to fix and commit.
