Charles Pritchard commented on HIVE-6163:
-----------------------------------------
Confirmed on my side as well -- you end up with part-m-00000 files from the
mapper in your home directory. I consider this a critical bug and a very simple
fix.

> Hi,
> OrcOutputFormat#getRecordWriter creates OrcRecordWriter instance using a file
> with relative path actually.
> return new OrcRecordWriter(new Path(name), OrcFile.writerOptions(conf));
> https://github.com/apache/hive/blob/7263b3bb1632b1a7c6ef5d2363e58020e1fdd756/ql/src/java/org/apache/hadoop/hive/ql/io/orc/OrcOutputFormat.java#L114
> The fix should be very simple, just as RCFileOutputFormat#getRecordWriter,
> append work output path as the parent:
> Path outputPath = getWorkOutputPath(job);
> Path file = new Path(outputPath, name);
