Dear HUE community,
We at NOKIA technologies, have been using the cloudera stack for our analytics based products since a few months. We have had a very good experience using it, specially the HUE enabled OOZIE workflow designer. It has made our lives much easier than before.
We have now decided to use HUE for the same purpose on our old clusters that do not run cloudera.
We followed instructions and installed HUE(and other required stuff) on our old clusters. But when start the UI in a browser, we see that HUE server just cannot communicate with webhdfs.
That webhdfs works fine is known from the fact the same GET command copied from HUE logs, works fine when run from the browser window and an entry is logged in the webhdfs log.
That hue cannot communicate with webhdfs is known because no request entry is logged in the webhdfs log when hue file browser is accessed via the HUE UI.
I have checked superuser configuration and privileges - and that is all fine. For simplicity, we have just one user for all services, which is also the hadoop superuser.
I paste the relevant logs below:
