--------------------------------------------
Summary: Update file deletion logic to support snapshot files
Key: HDFS-4092
URL: https://issues.apache.org/jira/browse/HDFS-4092
Project: Hadoop HDFS
Issue Type: Sub-task
Components: name-node
Reporter: Tsz Wo (Nicholas), SZE
Assignee: Tsz Wo (Nicholas), SZE
When snapshots are created, the blocks are shared among the snapshot files and the original file. Deletion of the snapshot file or the original file does not necessarily lead to deletion of the blocks. The deletion logic needs to be updated.
