Adding implementation to JDBC driver
------------------------------------
Key: HIVE-1536
URL: https://issues.apache.org/jira/browse/HIVE-1536
Project: Hadoop Hive
Issue Type: Improvement
Reporter: Sean Flatley
As a result of a Sprint which had us using Pentaho Data Integration with the
Hive database we have updated the driver. Many PreparedStatement methods have
been implemented. A patch will be attached tomorrow with a summary of changes.
Note: A checkout of Hive/trunk was performed and the TestJdbcDriver test cased
was run. This was done before any modifications were made to the checked out
project. The testResultSetMetaData failed:
java.sql.SQLException: Query returned non-zero code: 9, cause: FAILED:
Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MapRedTask

A co-worker did the same and the tests passed. Both environments were Ubuntu
and Hadoop version 0.20.2.
Tests added to the TestJdbcDriver by us were successful.
