Subject [jira] [Commented] (HIVE-1608) use sequencefile as the default for storing intermediate results
Date Mon, 08 Feb 2016 16:02:40 GMT


Chaoyu Tang commented on HIVE-1608:

[~brocknoland], [~ashutoshc] could you review the patch at your earliest convenience given
that so many test files have been changed? Thanks in advanced.
The change is straightforward:
1. code: change hive.query.result.fileformat default to use SequenceFilenew in order to default
support new line character in column.
2. test output files: change all input and output format of FileSinkOperator to SequenceFileInputFormat
and SequenceFileOutputFormat.

1. Some manual tests which also includes "insert overwrite [local] directory" that is actually
not affected by this change
2. Precommit tests.

> The only argument for having a text file for storing intermediate results seems to be
better debuggability.
> But, tailing a sequence file is possible, and it should be more space efficient
