Jake Low updated HDFS-8422: --------------------------- Attachment: HDFS-8422.001.patch > Recursive mkdir removes sticky bit when adding implicit u+wx to intermediate > directories > ---------------------------------------------------------------------------------------- > > Key: HDFS-8422 > URL: https://issues.apache.org/jira/browse/HDFS-8422 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 2.7.0 > Reporter: Jake Low > Assignee: Jake Low > Priority: Minor > Attachments: HDFS-8422.001.patch > > > When performing a recursive {{mkdirs}} operation, the NameNode takes the > provided {{FsPermission}} and applies it to the final directory that is > created. The NameNode also uses these permissions when creating intermediate > directories, except it promotes with {{u+wx}} (i.e. {{mode |= 0300}}) in > order to ensure that there are sufficient permissions on the new directory to > create further subdirectories within it. > Currently the code that does this permission promotion uses the > three-argument {{FsPermission}} constructor, which sets the sticky bit to > {{false}}. I think this is probably not the intended behaviour, so I'm > opening a bug. I'll attach a patch shortly that changes the behaviour so that > the sticky bit is always retained. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
