> Implement ChecksumFileSystem#getFileChecksum equivalent to HDFS for easy check

> Key: HADOOP-12326
> URL: https://issues.apache.org/jira/browse/HADOOP-12326
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 2.7.1

> Attachments: HADOOP-12326.001.patch

>
> If we have same-content files, one local and one remotely on HDFS (after
> downloading or uploading), getFileChecksum can provide a quick check whether
> they are consistent. To this end, we can switch to CRC32C on local
> filesystem. The difference in block sizes does not matter, because for the
> local filesystem it's just a logical parameter.
