Subject [jira] [Updated] (HIVE-4243) Fix column names in FileSinkOperator
Date Wed, 23 Sep 2015 17:12:05 GMT

Owen O'Malley updated HIVE-4243:
--------------------------------
    Attachment: HIVE-4243.patch

Ok, I added the changes to TypeDescription that Prasanth asked for. In particular, I added
a toJson method that prints the detailed (and formatted) print out of the type. I also changed
the constructors to be more to use withPrecision, withScale, and withMaxLength for the primitive
types that can have attributes.

After thinking about it more, I undid the change to TreeWriter.write's interface and just
added both the inspector and schema to the constructors. That let me most of the write methods
the same.

> 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.
