LiXin Ge created HADOOP-14424:
---------------------------------

             Summary: Add CRC32C performance test.
                 Key: HADOOP-14424
                 URL: https://issues.apache.org/jira/browse/HADOOP-14424
             Project: Hadoop Common
          Issue Type: Improvement
          Components: common
    Affects Versions: 3.0.0-alpha2
            Reporter: LiXin Ge
            Priority: Minor
             Fix For: 3.0.0-alpha2


The default checksum algorithm of Hadoop is CRC32C, so we'd better add a new test to compare
Crc32C chunked verification implementations.
This test is based on Crc32PerformanceTest, what I have done in this test is:
1.CRC32C performance test.
2.CRC32C is not supported by java.util.zip in JAVA JDK, so just remove it from this test.
3.User can choose either direct buffer or non-directly buffer to run this test manually.
