Ayappan created HDFS-6903:
-----------------------------
Summary: Crc32 checksum errors in Big-Endian Architecture
Key: HDFS-6903
URL: https://issues.apache.org/jira/browse/HDFS-6903
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Affects Versions: 2.4.1, 3.0.0
Environment: PowerPC RHEL 7 & 6.5 ( ppc64 - Big-Endian )
Reporter: Ayappan
Fix For: 2.4.1
Native Crc32 checksum calculation is not handled in Big-Endian Architecture.In
this case, the platform is ppc64. Due to this several testcases in HDFS module
fails.
