(Updated Dec. 13, 2013, 3:35 a.m.)
Review request for hive and Xuefu Zhang.
Changes
-------
Fixed formatting (tabs)
Fixed 'show create table' to support null format
Added testcase for CTAS
Bugs: HIVE-1466
https://issues.apache.org/jira/browse/HIVE-1466
Repository: hive-git
Description
-------
Support configurable null format for tables and writing out to directory.
Using a non-default null format is a bit while creating a table, and pretty
much impossible to export the data to local filesystem using insert overwrite
directory.
The patch enhances the SQL syntax to support 'NULL DEFINED AS' construct for
create table as well as insert overwrite directory.
