      Description

      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.
