Hello Why does Hue run Impala query as 'hue/master1@MY-REALM' instead my username 'ben'?   I get this error (even i'm logged-in as 'ben' user)   Your query has the following error(s): Request from user 'hue/master1@MY-REALM' with requested pool 'it' denied access to assigned pool 'root.it'   Previous to Cloudera 5.7 i think Cloudera had llama service and ran Impala query as 'llama' user. Now with Cloudera 5.7 I could have Impala without llama and have it's own Dynamic Resource Management. but problem is Hue runs query as hue/master1... user instead of my username.   Similar thing happens to Hive. Hive runs hive query as 'hive' user instead of my username. I found it pretty annoying..   Does anyone has better idea to this? Ben ... View more

I have to ask this question   Few years ago, before the redesign of Hue interface, I was able to configure dataset, data-in, data-out, input-events on Oozie Coordinators from Hue.   However lately with the redesign, I don't see them anymore. It looks like it's replaced with CRON field. WHY!!??   or am I missing something?   I'm using Cloudera 5.7 with Hue 3.9 Ben ... View more

Hi.   I setup Hue load-balancing following instructions on  http://www.cloudera.com/content/www/en-us/documentation/enterprise/latest/topics/cdh_hag_hue_config.html   So i have nginx running and everything seems working fine. However when I open a file from File Browswer (http://hueserver:8888/filebrowser/view/filepath) the page gets redirected to http://hue/filebrowswer/view/filepath, and shows page not found error   i think the unexpected "hue" hostname comes from the upstream name on nginx configuration.   Anyone has any idea how to fix this?   Thanks  Ben ...
