Subject [jira] [Commented] (HDFS-11084) OIV ReverseXML processor does not recognize sticky bit
Date Thu, 19 Jan 2017 08:39:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15829521#comment-15829521
] 

Akira Ajisaka commented on HDFS-11084:
--------------------------------------

Some comments from me:
* Would you rename the new directory from {{/tmp}} to {{/stickybit}} or something to specify
that the directory has sticky bit?
* Would you add a entry for the directory to {{writtenFiles}} to pass the regression test?

I'm thinking HADOOP-13508 should be backported to branch-2 as well? What do you think, [~jojochuang]?

> HDFS-10505 added a new feature OIV ReverseXML processor to generate a fsimage from a
xml file. However, if the files/directories in it has sticky bit, ReverseXML processor can
not recognize it due to HADOOP-13508.
> It seems HADOOP-13508 is an incompatible change in Hadoop 3. Would it be reasonable to
add an overloaded FsPermission constructor that uses RawParser so that it reads sticky bits
correctly? Or is it reasonable to backport HADOOP-13508 to branch-2?
