Subject error trying to setPermissions on hdfs file using api
Date Mon, 12 Sep 2011 23:25:31 GMT
I can get the file path/permissions but unable to change permissions. Below
is the snippet of code & error. What is the correct way of doing this?
Thanks.

FileSystem fileSystem = FileSystem.get(new Configuration());

FileStatus fileStatus = fileSystem.getFileStatus(new Path(
"/tmp/hbase/bulk_out"));

System.out.println("Files: " + fileStatus.getPath());

System.out.println("Changing perms from: " + fileStatus.getPermission());

fileSystem.setPermission(fileStatus.getPath(),
FsPermission.createImmutable((short) 0777));

This results in:

Files: hdfs://06.hadoop.dev:54310/tmp/hbase/bulk_out

Changing perms from: rwxrwxrwx
