HUE no longer sees impala or have after restart

I had Hive and Impala working on HUE before 

Versions HUE 3.7

Clouderan Manager 5.4.11


I recently restarted HUE

and HUE no longer sees Impala or hive




Configuration files located in /run/cloudera-scm-agent/process/7850-hue-HUE_SERVER 

Potential misconfiguration detected. Fix and restart Hue.

Hive Editor	The application won't work without a running HiveServer2.
Impala Editor	No available Impalad to send queries to.



 When I run a query I get cannot import name TGetLogReq



Error log shows the following 


[03/Apr/2017 00:16:53 -0700] wsgiserver   ERROR    WSGI (<WorkerThread(CP WSGIServer Thread-19, started 140018618201856)>) error: [('SSL routines', 'SSL23_WRITE', 'ssl handshake failure')]

Re: HUE no longer sees impala or have after restart


Romain posted on Hue user group that I had a conflict in python libraries and indeed I did

I had Impyla and Airflow installed as part of the main lib/distro instead of a controlled "virtualized" environment

This caused the  conflict.  


Unfortunately both Impyla and Airflow could not be uninstalled with a simple pip uninstall command

Had to manually compare directories from my staging environment and remove several of the directories that could be potentially conflicting

These include:

  • hive_metastore
  • hive_thrift_py
  • pyhive
  • hive_serde
  • impala
  • PyHive
  • TCLIService
  • hive_service
  • impyla
  • thrift

Once the directories where removed from /usr/local/lib/python2.7/dist-packages and restarted HUE, it was querying again.    Many kudos to Romain
