Jing Zhao created HDFS-5476: ------------------------------- Summary: Snapshot: clean the blocks/files/directories under a renamed file/directory while deletion Key: HDFS-5476 URL: https://issues.apache.org/jira/browse/HDFS-5476 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.2.0 Reporter: Jing Zhao Assignee: Jing Zhao
Currently DstReference#destroyAndCollectBlocks may fail to clean the subtree under the DstReference node for file/directory/snapshot deletion. Use case 1: # rename under-construction file with 0-sized blocks after snapshot. # delete the renamed directory. We need to make sure we delete the 0-sized block. Use case 2: # create snapshot s0 for / # create a new file under /foo/bar/ # rename foo --> foo2 # create snapshot s1 # delete bar and foo2 # delete snapshot s1 We need to make sure we delete the file under /foo/bar since it is not included in snapshot s0. -- This message was sent by Atlassian JIRA (v6.1#6144)
