Wei-Chiu Chuang updated HDFS-9123: ---------------------------------- Attachment: HDFS-9123.002.patch > 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 > Attachments: HDFS-9123.001.patch, HDFS-9123.002.patch > > > 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)
