I am using CDH 5.2. I have a single node setup of cloudera. I am trying to retrive a single column from a table in hive database using hive editor in Hue web interface. When I fire the query, the job hangs, and does not proceed to map reduce.
Please note that, there is no error logged in any of the log files (Node manager log, Resource Manager log or hive log). There are just INFO and warning messages.
I am using hiveserver2 on port 17000.
Command I am trying to execute - select emp_id from emp3;

I was finally able to get this to work by increasing the yarn.nodemanager.resource.memory-mb value from 1 GB (the default) to 6 GB. Apparently this is a resource issue, but there are no warnings that I could find that state this clearly.
