> Key: HIVE-18206
> URL: https://issues.apache.org/jira/browse/HIVE-18206
> Project: Hive
> Issue Type: New Feature
> Affects Versions: 1.2.1, 2.1.1, 2.2.0, 3.0.0
> Reporter: Wang Haihua
> Assignee: Wang Haihua
> Attachments: HIVE-18206.1.patch, HIVE-18206.2.patch
>
>
> 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}}
