Subject [jira] [Updated] (HIVE-3125) sort_array doesn't work with LazyPrimitive
Date Wed, 13 Jun 2012 11:21:42 GMT

     [ https://issues.apache.org/jira/browse/HIVE-3125?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Philip Tromans updated HIVE-3125:
---------------------------------

    Attachment: HIVE-3125.1.patch.txt

I'm not entirely sure if this is the right way to fix this. The right thing to do may well
be to make LazyInteger Comparable, but I thought it'd be best for me to stay out of Hive's
serde stuff. I'm still a little new round here...

This fixes it by using the ObjectInspectorUtils compare() method.

> The sort_array function doesn't work against data that's actually come out of a table.
The test suite only covers constants given in the query.
> If you try and use sort_array on an array from a table, then you get a ClassCastException
that you can't convert LazyX to Comparable.
