title: Not able to access Hive Tables through JDBC in Hortonworks Sandbox 2.0
body: <p>I am using Hortonworks Sandbox 2.0. I tried the following program in the Eclipse IDE, but was not table to access my Hive tables. Got the following errors. What do I have to do to resolve this?</p>
  
  <p>I used this also: <code>hive –service hiveserver</code>, and got <em>Not able to connect</em>. I am using VMware.</p>
