> Key: HADOOP-9155
> URL: https://issues.apache.org/jira/browse/HADOOP-9155
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 2.0.2-alpha
> Reporter: Binglin Chang
> Assignee: Binglin Chang
> Priority: Minor
> Attachments: HADOOP-9155.patch, HADOOP-9155.v2.patch

> 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.
