Access Hive Tables in SQLClient but not from the Putty

Question

I am new to Hive, MapReduce and Hadoop. I am using Putty to connect to hive table and access records in the tables. So what I did is- I opened Putty and in the host name I typed

Answer 1

What are you doing with Putty is SSH'ing into a machine with Hive installed and set up. Then you are issuing Hive queries from the Hive command line. That is one way of issuing Hive queries. There are other ways that don't require SSH'ing, one you probably need is connection via JDBC.

Here is an article which describes how to connect to a Hive installation on Amazon's EMR cluster using SQuirreL via JDBC. The article might appear to be Amazon specific but it's not. As long you have Hive server running on one of the nodes of the cluster and no firewall impeding connection between the client machine and one running Hive, you should be able to connect.

A couple things you might want to keep in mind related to the above link:

• You can ignore step 3 where it asks you to create a SSH tunnel unless you are using EMR.
• The port that you enter in your connection URI might be different in your case. Replace localhost with the fully qualified domain name of the machine that Hive is running on. To find out which port Hive server is listening on, you can look into your Hive server nanny log file present in the log directory (whose location depends on your installation) or run a simple netstat -a command. I believe 10000 is the default port number, so it might make sense to try out 10000 directly.
