Subject [GitHub] orc issue #163: ORC-162. Handle 0 byte files as empty ORC files.
Date Tue, 29 Aug 2017 22:34:01 GMT
Github user prasanthj commented on the issue:

    https://github.com/apache/orc/pull/163
  
    Hive creates empty files only for MR to support bucketed joins. Tez doesn't create empty
bucket files anymore. Hive currently discards empty files during split generation. We can
do similar thing in Orc's version of OrcInputFormat (or add EmptyFilePathPattern to ignore
0 length files or files <= MAGIC.length). Creating splits for empty is anyway useless.
As far as calling the Reader's directly with a empty file path, we can treat it as empty file
with struct<>.
