that ends up in the recovery information for Tez.

1) Does it have to?
2) Can we just use the binary form like the HBase metastore cache? The paths in
LocalCache and RemoteCache should be relatively easy to reuse/reconcile.
> Enable hive.orc.splits.include.file.footer by default

> 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.
