Subject [jira] [Commented] (HADOOP-9155) FsPermission should have different default value, 777 for directory and 666 for file
Date Thu, 03 Jan 2013 19:04:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13543194#comment-13543194

Aaron T. Myers commented on HADOOP-9155:

Ah, sorry, I just noticed [this comment|https://issues.apache.org/jira/browse/HADOOP-9155?focusedCommentId=13537770&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13537770]
of yours explaining why you continue to use {{FsPermission.getDefault}} in a few places. It
seems fine to me to continue to use that in the tests, but I do think we should use the new
{{FsPermission.getDirDefault}} call in the main code.

>             Project: Hadoop Common
>          Issue Type: Bug
>    Affects Versions: 2.0.2-alpha
>            Reporter: Binglin Chang
>            Assignee: Binglin Chang
>            Priority: Minor

> The default permission for {{FileSystem#create}} is the same default as for {{FileSystem#mkdirs}},
namely {{0777}}. It would make more sense for the default to be {{0666}} for files and {{0777}}
for directories.  The current default leads to a lot of files being created with the executable
bit that really should not be.  One example is anything created with FsShell's copyToLocal.
> For reference, {{fopen}} creates files with a mode of {{0666}} (minus whatever bits are
set in the umask; usually {{0022}}.  This seems to be the standard behavior and we should
follow it.  This is also a regression since branch-1.
