HUE no longer sees impala or have after restart

scratch28 — Tue, 21 Apr 2026 13:47:00 GMT

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')]

Fixed

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
