I want to use Hue (that I got from http://gethue.com/hue-4-1-is-out/ ) only using the connection with Solr (nothing else).
I have solr 6.6.0 with already some collections with, on every collection, some documents.
I have a linux system (64 bit), and I have installed Hue from the latest tar.gz file : until this is all ok .
Then, I followed exactly the instructions of the web page http://gethue.com/solr-search-ui-only/#comment-72349
in order to connect Hue with my Solr system .
But, unfortunately, when I login to Hue, it performs the authentication without problem, but (after the authentication) it gives me “500 server error” .
If I see the errors.log file I note these errors:
[30/Jan/2018 08:56:02 -0800] fsmanager ERROR Failed to get filesystem called “default” for “adl” schema: Filesystem not configured for adl
[30/Jan/2018 08:56:02 -0800] fsmanager ERROR Failed to get filesystem called “default” for “s3a” schema: Filesystem not configured for s3a
[30/Jan/2018 08:56:11 -0800] views ERROR Could not create home directory at login for admin.
[30/Jan/2018 08:14:22 -0800] oozie_batch ERROR Oozie application is not enabled: ‘Config’ object has no attribute ‘get’
I suspect that I also must have cloudera manager in order to work with Hue (or at least I must have Hadoop configured in a proper mode). I do not need cloudera manager and Hadoop for my project: is it possible to use Hue with Solr , without Hadoop and cloudera manager?
Thank you for a possible help.

> What did you put in app_blacklist?
I put exactly as described in the web page http://gethue.com/solr-search-ui-only/#comment-72349
so I put:

Unfortunately also with your suggestion it does not work:
I also removed, in the blacklist, indexer,
so actaully in the blacklist I have:
Then, if I restart hue and I perform the login procedure in the web browser,
after the login procedure it appears the message (in the web browser)
"A server error occurred. Please contact the administrator.".
I noted that in the error.log file are written these new lines:

I remember you that, in my computer (that has a the ditribution linux mint 18.1 (64 bit))
there is only installed solr ver. 6.6.0 that runs in correct mode
(I verified it) in http://localhost:8983 and there are some collections (with some documents inside).
I also remember you that in my computer there is not haddop running.
Could you help me in order to solve the problem?

What is Hue Master ? And How could I get it ?
I installed HUE, from the tar.gz package
that I got from http://gethue.com/hue-4-1-is-out/
and after I have installed the above package
(following the instruction in included README file).
And then I followed the instrunction in http://gethue.com/solr-search-ui-only/#comment-72349 .
I performed the above operations because I only need
Hue with solr (nothing else).
Is it mandatory (to work with Hue and Solr)
also to have additional packages? (cloudera manager and/or hadoop, or postgres db, or other?).

> we would recommend to just remove the
> other apps permission in the default group:
If I go in the section of permission
of the "default" group I see a lot of modules
that I can tick .
So, if I understand well, I I want only to use solr collections,
I have only to tick the module "search.access" and nothing else?
Could you give me the exact list (of permission in "default" group)
of modules to tick?
