----------------------------------
Summary: {{DistributedFileSystem#getFileChecksum}} of a
snapshotted file includes non-snapshotted content
Key: HDFS-7682
URL: https://issues.apache.org/jira/browse/HDFS-7682
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.7.0
Reporter: Charles Lamb
Assignee: Charles Lamb
DistributedFileSystem#getFileChecksum of a snapshotted file includes
non-snapshotted content.
The reason why this happens is because DistributedFileSystem#getFileChecksum
simply calculates the checksum of all of the CRCs from the blocks in the file.
But, in the case of a snapshotted file, we don't want to include data in the
checksum that was appended to the last block in the file after the snapshot was
taken.
