> 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.
