Dear All,   I am quite new to Hadoop environment. Can experts please help with the below queries :   Things done until now :   1. I have Cloudera Hadoop running on AWS (ubuntu 14). 2. Have successfully installed Cloudera manager and a cluster is also created. The web link for CM and HUE are functioning good. 3. Have loaded csv files on HDFS and created hive tables ( as per guidance provided by experts here in this forum). 4. I am able to access these tables from Impala and create some simple graphs.   Questions :   1. we are using a reporting tool called BIRST. I would like to connect BIRST to the Hadoop environment. Should I directly connect to Hive and access the tables created in Hive.   2. Should I use JDBC connectivity.   3. In BIRST for JDBC connectivity, I need the driver name and  connection string. I am not able to find the connection details in the cloudera manager for Hive. Is there any pre-requisities required.   Thanks.   ... View more
