[3/3] git commit: HDT-41: Provide existing MR functionality - ported Mapper/Reducer/Partioner/Driver Wizards - ported Image lookup - ported Map-reduce project wizard - using runtimes from specified hadoop location rather as runtime jars packed in plugin

Posted by rs...@apache.org.
HDT-41: Provide existing MR functionality
- ported Mapper/Reducer/Partioner/Driver Wizards
- ported Image lookup
- ported Map-reduce project wizard
- using runtimes from specified hadoop location rather as runtime jars packed in plugin
- ported 'Run On Hadoop'
- ported Hadoop location preference at Window->Preferences->Hadoop
- ported clusterView
- Modified hadoop perspective to contain clusterView
