> 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

> 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.
