[jira] [Created] (HADOOP-7445) Implement bulk checksum verification using efficient native code

Implement bulk checksum verification using efficient native code
----------------------------------------------------------------

                 Key: HADOOP-7445
                 URL: https://issues.apache.org/jira/browse/HADOOP-7445
             Project: Hadoop Common
          Issue Type: Improvement
          Components: native, util
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


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.
