> Allow IFile reducer merge-sort to disable crc32 checksums
> ---------------------------------------------------------

> Key: TEZ-1719
> URL: https://issues.apache.org/jira/browse/TEZ-1719
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.6.0
> Reporter: Gopal V
> Labels: Performance

> Next-gen filesystems like BTRFS and ZFS provide their own checksumming for
> disk data.
> Using PureJavaCrc32 for data written for temporary spills to such filesystems
> is a complete waste of CPU resources.
