Subject [jira] [Commented] (HDFS-6258) Namenode server-side storage for XAttrs
Date Wed, 30 Apr 2014 18:18:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13985864#comment-13985864
] 

Charles Lamb commented on HDFS-6258:
------------------------------------

A few minor nits.

In XAttrPermissionFilter.java, please change the javadoc to read:

+/**
+ * There are 4 types for extended attribute <XAttr>:

There are four types of extended attributes <XAttr> defined by the
following namespaces:

USER -- extended user attributes: these can be assigned to files and
directories to store arbitrary additional information. The access
permissions for user attributes are defined by the file permission
bits.

TRUSTED -- trusted extended attributes: these are visible/accessible
only to/by the super user.

SECURITY -- extended security attributes: these are used by the HDFS
core for security purposes and are not available through admin/user
API.

SYSTEM -- extended system attributes: these are used by the HDFS
core and are not available through admin/user API.

Formatting nit, there's an extra newline right before the last } closing the class.

XAttrStorage.java:

+ * XAttrStorage is used to read and set xattrs for inode.
