Hi, Is it possible to export ORC files using Sqoop? I need to export from Hive to another DBMS which also supports ORC, therefore I would prefer to directly export ORC files without any needs to do conversions.

I want to submit a job to Yarn, which has dependencies to third party libraries. Map reduce jobs fail as they can't load these third party libraries on remote Hadoop nodes. Can I use Yarn in someway, to submit a whole package (including 3rd party libs), so MR jobs can successfully load them?

Thanks for this helpful article. I'm a little bit confused about how PutHiveQL can receive a HQL DDL/DML command. Do you have an example of a flow in which a PutHiveQL process receives a command from another process?

Thanks for your comment. I just solved the problem after 2 days of struggling. There reason was the proxy settings set on my machine by the company I work for. I just added 'sandbox.hortonworks.com' domain name to the proxy bypass list. Also, in order to make webhdfs connection to sandbox from another CentOS VM I added 'sandbox.hortonworks.com' to no_proxy variable at /etc/bashrc of the CentOS and it worked! Thanks 🙂

@zblanco I add '127.0.0.1 sandbox.hortonworks.com' to the Host machine hosts file, however I still get dns error when I entered something like 'http://sandbox.hortonworks.com:8888/' in my browser. (I also restarted my browser and machine, the the problem still exists). I can ping 'sandbox.hortonworks.com' and it redirects my ping to 127.0.0.1. But do you know why dns is looked up when I use the domain name in browser or in a webhdfs connection to sandbox?
