File Permission Issue using Distributed Cache of Hadoop-2.2.0
Hi Experts,
The original local file has execution permission, and then it was
distributed to multiple nodemanager nodes with Distributed Cache feature of
Hadoop-2.2.0, but the distributed file has lost the execution permission.
However I did not encounter such issue in Hadoop-1.1.1.
Why this happened? Some changes about 'dfs.umask' option or related staffs?
Thanks!

My colleague found distcp tool does miss execution permission as well.
I also found some difference between hadoop 1.x and hadoop 2.x:
- On Hadoop 2.2.0, I can use command 'hadoop dfs -chmod 755 test01' to add
execution permission on hdfs file test01: '*-rwxr-xr-x* 1 admin
admin 8465 2014-05-30 16:45 test01'
- However, on Hadoop 1.1.1, I can not add execution on hdfs file using such
command
I have two further questions:
*- Does it means that HDFS 2.2.0 has execution permission, but HDFS 1.1.1
has not?*
*- If HDFS 2.2.0 has execution permission, how to keep the execution
permission after putting file onto hdfs?*
This issue confuses us for a long time, and any comments/suggestions will
be appreciated!

Hi,
On Hadoop 1.1.1, I did a test on execution permission as below:
1. Set '*dfs.umaskmode*' to '*000*' in hdfs-site.xml
2. The permission of the test file on linux local file system is '
*-rwxr-xr-x* 1 admin admin 12297 5?? 30 01:44 test'
3. Put the test file to hdfs using command 'hadoop dfs -put test test'
Result:
In hdfs, the permission of the uploaded file is '*-rw-rw-rw-* 1 admin
supergroup 12297 2014-05-30 02:57 /user/admin/test'
As the hdfs umask value is set to '000', I think the uploaded file's
permission should be '-rwxr-xr-x' as well, but the result is different. Why?

Hi Experts,
The original local file has execution permission, and then it was distributed to multiple nodemanager nodes with Distributed Cache feature of Hadoop-2.2.0, but the distributed file has lost the execution permission.
However I did not encounter such issue in Hadoop-1.1.1.
Why this happened? Some changes about 'dfs.umask' option or related staffs?
Thanks!

Subject: Re: File Permission Issue using Distributed Cache of Hadoop-2.2.0
Is this possible a Hadoop issue? Or any options is wrong in my cluster?

Hi Experts,
The original local file has execution permission, and then it was distributed to multiple nodemanager nodes with Distributed Cache feature of Hadoop-2.2.0, but the distributed file has lost the execution permission.
However I did not encounter such issue in Hadoop-1.1.1.
Why this happened? Some changes about 'dfs.umask' option or related staffs?
Thanks!
