------------------------------------
Summary: Native implementation of java Checksum interface
Key: HADOOP-10859
URL: https://issues.apache.org/jira/browse/HADOOP-10859
Project: Hadoop Common
Issue Type: Improvement
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Minor
Some parts of our code such as IFileInputStream/IFileOutputStream use the java
Checksum interface to calculate/verify checksums. Currently we don't have a
native implementation of these. For CRC32C in particular, we can get a very big
speedup with a native implementation.
