I ran the tests in multiple JDK versions ranging from JDK 1.8.0_05 to JDK
1.8.0_102 on CentOS 6.5 (I tested both with/without native libisal library),
and I got the following error for all tests in TestFileChecksum.:
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 7.46 sec <<<
FAILURE! - in org.apache.hadoop.hdfs.TestFileChecksum

Maybe it's just my env issue. Can't tell.
