Pengcheng Xiong commented on HIVE-13828:
----------------------------------------

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.

> 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.
