Subject [jira] Updated: (HIVE-624) Fix bug in TypeConverter
Date Fri, 10 Jul 2009 07:15:14 GMT

     [ https://issues.apache.org/jira/browse/HIVE-624?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zheng Shao updated HIVE-624:
----------------------------

    Attachment: HIVE-624.1.patch

This patch fixes the problem by rewriting all the converters.

The converters are expanded to a class hierarchy so it can reuse the returned conversion result
(a Writable object) more easily.


I also added the Settable*ObjectInspector which provides a delegated way of setting the value
of an object and creating new objects.

It also adds one new test case for the converters, and one more client positive test case.

> There is a bug in the Converter - we are converting all objects to Primitive Java objects
instead of Writable.
> This has caused some queries to fail:
> {code}
> SELECT IF(false, 1, cast(2 as smallint)) + 3 FROM any_table;
> {code}
