HUE Errors

I installed HUE, following the Hortornworks documentation:

http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_installing_manually_book/content/ch_installing_hue_chapter.html

When I first signed into HUE, I got the error “Could not create home directory.”. When I try different components in Hue, I get the following error messages for Beeswax, hcatalog, WebHdfs and Oozie:

QueryServerException at /beeswax/
Bad status for request TOpenSessionReq(username=’hue’, password=’hue’, client_protocol=4, configuration={‘hive.server2.proxy.user’: u’hdfs’}):

QueryServerException at /hcatalog/
Bad status for request TOpenSessionReq(username=’hue’, password=’hue’, client_protocol=4, configuration={‘hive.server2.proxy.user’: u’hdfs’}):

WebHdfsException at /filebrowser/

An error with Oozie occurred.
HTTPConnectionPool(host=’localhost’, port=11000): Max retries exceeded with url: /oozie/v1/jobs?len=100&doAs=hue&filter=&user.name=hue&timezone=America%2FLos_Angeles&jobtype=wf (Caused by <class ‘socket.error’>: [Errno 111] Connection refused)

I can’t figure out what I did wrong or I am missing. Please HELP!!!
