Nitpick you may consider fixing during commit, source should be sources since the check is enforced for each source file. That's a good idea. Thanks! Here is patch v003 with that change. > Document types of permission checks performed for HDFS operations. > ------------------------------------------------------------------ > > Key: HDFS-9552 > URL: https://issues.apache.org/jira/browse/HDFS-9552 > Project: Hadoop HDFS > Issue Type: Improvement > Components: documentation > Reporter: Chris Nauroth > Assignee: Chris Nauroth > Attachments: HDFS-9552.001.patch, HDFS-9552.002.patch, HDFS-9552.003.patch, hadoop-site.tar.bz2 > > > The HDFS permissions guide discusses our use of a POSIX-like model with read, write and execute permissions associated with users, groups and the catch-all other class. However, there is no documentation that describes exactly what permission checks are performed by user-facing HDFS operations. This is a frequent source of questions, so it would be good to document this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
