-------------------------------------------
Summary: Make OrcFile's "enforceBufferSize" user-settable.
Key: HIVE-17600
URL: https://issues.apache.org/jira/browse/HIVE-17600
Project: Hive
Issue Type: Improvement
Components: ORC
Affects Versions: 2.2.0, 3.0.0
Reporter: Mithun Radhakrishnan
Assignee: Mithun Radhakrishnan
This is a duplicate of ORC-238, but it applies to {{branch-2.2}}.
Compression buffer-sizes in OrcFile are computed at runtime, except when
enforceBufferSize is set. The only snag here is that this flag can't be set by
the user.
When runtime-computed buffer-sizes are not optimal (for some reason), the user
has no way to work around it by setting a custom value.
I have a patch that we use at Yahoo.
