Suresh Srinivas commented on HDFS-4605:
---------------------------------------
bq. no partial blocks in the middle.
I assume that this means the block in the middle should be of size block
length. However, one of the things I have been thinking of is variable length
block sizes - see HDFS-3689. It would also be good not to have block size as
multiple of crc chunk size. Though these are currently enforced, there are
advantages to not enforce this.
> Implement block-size independent file checksum

> Key: HDFS-4605
> URL: https://issues.apache.org/jira/browse/HDFS-4605
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode, hdfs-client
> Affects Versions: 3.0.0
> Reporter: Kihwal Lee

> The value of current getFileChecksum() is block-size dependent. Since
> FileChecksum is mainly intended for comparing content of files, removing this
> dependency will make FileCheckum in HDFS relevant in more use cases.
