[jira] Commented: (HIVE-1536) Add support for JDBC PreparedStatements

["John Sichi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-1536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12898381#action_12898381 ] 

John Sichi commented on HIVE-1536:
----------------------------------

Sounds like an environmental problem, since I don't think I've heard reports of failures on that test elsewhere.  Can you check hive-trunk/build/ql/tmp/hive.log after the test run to find the exception details?  (Search for the text of the select statement executed by that test.)

> 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:
