Key: HADOOP-7446
URL: https://issues.apache.org/jira/browse/HADOOP-7446
Project: Hadoop Common
Issue Type: Improvement
Components: native
Reporter: Todd Lipcon
Once HADOOP-7445 is implemented, we can get further performance improvements by implementing CRC32C using the hardware support available in SSE4.2. This support should be dynamically enabled based on CPU feature flags, and of course should be ifdeffed properly so that it doesn't break the build on architectures/platforms where it's not available.
