Subject [jira] [Updated] (HIVE-4243) Fix column names in FileSinkOperator
Date Wed, 09 Sep 2015 21:08:45 GMT

     [ https://issues.apache.org/jira/browse/HIVE-4243?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Prasanth Jayachandran updated HIVE-4243:
----------------------------------------
    Attachment: HIVE-4243.tmp.patch

[~owen.omalley] Can this change be made generic up top at FSOp layer? I am attaching a patch
that does the same in FSOp and using the dest table's Object Inspector. I am not sure if we
have to go through whole lot of TypeDescription changes.

> All of the ObjectInspectors given to SerDe's by FileSinkOperator have virtual column
names. Since the files are part of tables, Hive knows the column names. For self-describing
file formats like ORC, having the real column names will improve the understandability.
