Ning Zhang updated HIVE-1598:

    Attachment: HIVE-1598.patch

This patch only add support for using SequenceFile as query result. There are still questions
on whether we should use it for script operator or not. Will open another JIRA if needed.

> Hive query's result is written to a temporary directory first and then FetchTask takes
the files and display it to the users. Currently the file format used for the resulting file
is TextFile format. This could cause incorrect result display if some string typed column
contains new lines, which are used as record delimiters in TextInputFormat. Switching to SequenceFile
format will solve this problem.
