> Once HADOOP-7444 is implemented ("bulk" API for checksums), good performance
> gains can be had by implementing bulk checksum operations using JNI. This
> JIRA is to add checksum support to the native libraries. Of course if native
> libs are not available, it will still fall back to the pure-Java
> implementations.
