Subject [jira] [Commented] (HIVE-1402) Add parallel ORDER BY to Hive
Date Sun, 23 Jun 2013 03:16:21 GMT


Edward Capriolo commented on HIVE-1402:

Navis. Nice work all tests pass. One thing I noticed.

        for (FileStatus status : fs.globStatus(new Path(inputPath, ".sampling*"))) {
+          sampler.addSampleFile(status.getPath(), job);
+        }

For hadoop hidden files by convention start with '_' not '.' . Does it make sense to say "_sampling*"
here. Possibly put this as a constant at the top of the file.

So please fix the above thing if you think it is a good idea, and regenerate the patch so
it applies clean please.

Then I will commit.
