Subject [jira] [Updated] (HIVE-9450) [Parquet] Check all data types work for Parquet in Group By operator
Date Fri, 23 Jan 2015 16:06:36 GMT

     [ https://issues.apache.org/jira/browse/HIVE-9450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dong Chen updated HIVE-9450:
----------------------------
    Attachment: HIVE-9450.patch

Upload a patch to add tests for data types used in group by operator, and fix CHAR/VARCHAR
bug.

Root cause is in {{WritableHiveCharObjectInspector.copyObject()}}. As described in HIVE-8205,
the object inspector should handle the conversion of Text writable. We add this special handling
here. Same for {{WritableHiveVarcharObjectInspector.copyObject()}}.
