> OrcFileMergeOperator does not use correct compression buffer size

> Key: HIVE-12450
> URL: https://issues.apache.org/jira/browse/HIVE-12450
> Project: Hive
> Issue Type: Bug
> Components: ORC
> Affects Versions: 1.2.0, 1.3.0, 1.2.1, 2.0.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Critical
> Attachments: HIVE-12450.1.patch, HIVE-12450.2.patch,

>
>
> OrcFileMergeOperator checks for compatibility before merging orc files. This
> compatibility check include checking compression buffer size. But the output
> file that is created does not honor the compression buffer size and always
> defaults to 256KB. This will not be a problem when reading the orc file but
> can create unwanted memory pressure because of wasted space within
> compression buffer.
> This issue also can make the merged file unreadable under certain cases. For
> example, if the original compression buffer size is 8KB and if
> hive.exec.orc.default.buffer.size is set to 4KB. The merge file operator will
> use 4KB instead of actual 8KB which can result in hanging of ORC reader (more
> specifically ZlibCodec will wait for more compression buffers).
> {code:title=jstack output for hanging issue}
