Wei-Chiu Chuang created HDFS-9123: ------------------------------------- Summary: Validation of a path ended with a '/' Key: HDFS-9123 URL: https://issues.apache.org/jira/browse/HDFS-9123 Project: Hadoop HDFS Issue Type: Bug Components: fs Reporter: Wei-Chiu Chuang Assignee: Wei-Chiu Chuang Priority: Minor
HDFS forbids copying from a directory to its subdirectory (e.g. hdfs dfs -cp /abc /abc/xyz) as otherwise it could cause infinite copying (/abc/xyz/xyz, /abc/xyz/xyz, /abc/xyz/xyz/xyz,... etc) However, if the source path is ended with a '/' path separator, the existing validation for sub-directories fails. For example, copying from / to /abc would cause infinite copying, until the disk space is filled up. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
