----------------------------------------
Hello, I am deferring this to Hive 3.0 as we are going to cut the first RC and
it is not marked as blocker. Please feel free to commit to the branch if this
can be resolved before the release.
> Enable hive.orc.splits.include.file.footer by default

> Project: Hive
> Issue Type: Improvement
> Components: ORC
> Reporter: Rajesh Balamohan
> Priority: Minor
>
> As a part of setting up the OrcInputFormat.getRecordReader in the task side,
> hive ends up opening the file path and reads the metadata information. If
> hive.orc.splits.include.file.footer=true, this metadata info can be passed on
> to task side which can help reduce the overhead. It would be good to
> consider enabling this parameter by default.
