You can connect to Hive in two modes. Through thrift server and embedded mode. By seeing your url localhost:10000/default, it looks like you are trying to connect to the thrift sever. So please ensure that you are have started the hive thrift server by the following command.

    $ hive --service hiveserver

If you want to connect in embedded mode. you should give the url as

   jdbc:hive://

To use the embedded mode you should add the hive/conf and the jars in hive/lib to your classpath.

It is to be noted that, use of the Thrift server is not thread safe as of now.

Can you please explain a bit more, I mean you said you are using JDBC to connect to hive. If this is so, are you using HiveMetaStoreClient or something else.

@Charnjeet Perhaps the port 10000 is already in use by some other process. Please check that once.
