Colin Patrick McCabe updated HADOOP-9155:
-----------------------------------------
Description:
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.
was:
Currently umask works differently as linux convention, which is:
The default umask 0002 is used for regular users.
The default umask for the root user is 0022.
For directories, the base permissions are 0777 and for files 0666.
> FsPermission should have different default value, 777 for directory and 666
> for file
