Subject [jira] Commented: (HDFS-126) Permission configuration files should use octal and symbolic
Date Thu, 20 Aug 2009 03:42:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745295#action_12745295
] 

Allen Wittenauer commented on HDFS-126:
---------------------------------------

this is one of those things where i think it is acceptable to break existing users, given
proper release notes and enough warning.  really.  if we are willing to break api's then breaking
something as relatively minor as permissions in the conf file does not seem like that big
of deal.

perhaps this will be the jira that finally provides 'upgrade' notes instead of just 'release'
notes, like most real world operating systems.

> Currently, the settings for the default umask in Hadoop configuration files require the
input format be in decimal.  Considering that every admin in the world thinks of permissions
in octal and/or symbolic format, the config files should really use those two formats and
drop decimal.
> [... and, yes, I'm aware this breaks backwards compatibility.  But in this case, I think
that is perfectly acceptable.]
