Hi @jmarcopoulos ,   Do you have Cloudera Manager for your cluster? If yes, you can update following config.   It turned out that for Debian or Ubuntu OSs, we need configure Hue's Load Balancer Advanced Configuration Snippet (Safety Valve) for httpd.conf with "MergeSlashes OFF", "Save Change" and restart Hue to avoid this missing slash error for s3 file browser.     Or you can use hue's server port: 8888 instead of hue's load balancer port:8889 to work around this issue.   This issue seems only happening for Debian and Ubuntu env. Centos/Redhat, Slesus are working fine.   Hope this helps!     Weixia   ... View more

Hi @maziyar,   We tried in house upgrade cluster from CDH5.16 to CDH6.1 without Solr being installed. We can't reproduce the issue. Hue works as expected.   Your hue config lists the "solr_url: https://localhost:8983/" under "search" is a bit suspicious though. If Solr is not installed on the cluster, you should be able to see "search" in your app_blacklist in your hue.ini as following:   [desktop] app_blacklist=search   It's not clear how your cluster ends up with this status. One suggestion can be adding "search" in the app_blacklist as above and restart Hue. It should be able to resolve your issue.    Please let us know if it helps.   Thanks!   Weixia ... View more
