> Merge configuration parameter, like {{hive.merge.size.per.task}} , decide the average file after merge stage.
> But we found it only work for file format like {{Textfile/SequenceFile}}. With {{RC/ORC}} file format, it {{does not work}}.
> For {{RC/ORC}} file format we found the file size after merge stage, depends on parameter like {{mapreduce.input.fileinputformat.split.maxsize}.
> it is better to use {{hive.merge.size.per.task}} to decide the the average file size for RC/ORC fileformat, which results in unifying.
> Root Cause is for RC/ORC file format, merge class is {{MergeFileTask}} instead of {{MapRedTask}} for Textfile/SequenceFile. And {{MergeFileTask}} just has not accept the configuration value in MergeFileWork, so the solution is passing it into {{MergeFileTask}}
