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.

Many thanks. It was really useful for beginners like me. Do you have any idea how can i access this data from other reporting tools. In our case, we use BIRST reporting tool. However I am not able to establish connection to HIVE tables. Is there any link, which I can refer to establish the JDBC. Warm Regards, Chandra.
