Charles Lamb created HDFS-7682: ---------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
