Review request for hive and Carl Steinbach.
Changes
-------
Rebased the patch and reran the TestJdbcDriver test.
Summary
-------
Added a method to get result schema from a Task. The ExplainSemanticAnalyzer
invokes this to get the schema for explain statement which is a single string
column.
This addresses bug Hive-727.
