Hive action

The general schema for Hive action is as follows:

<action>
  <job-tracker>        // Job tracker details
  <name-node>          // Name node details
  <prepare>            // Create or Delete directory
  <job-xml>            // Any job xml properties
  <configuration>      // Hadoop job configuration
  <script>             // Hive script to run
  <param>              // Parameters to hive script
  <argument>           // Arguments
  <file>               // Any files needed to run job
  <archive>            // Any job dependencies (jar etc)
</action>
