Hi, I was looking at the following link and reading about hdfs permissions (my hadoop version is 20.205)
http://hadoop.apache.org/common/docs/r0.20.205.0/hdfs_permissions_guide.html I find this dfs.umask property particularly useful, but I can't find this property in my hdfs-default.xml doc I was looking around why umask is not working and stumbled on this and it cleared some doubts. https://issues.apache.org/jira/browse/HADOOP-6234 What I am trying to do with umask is set it to *dfs.umaskmode = 077* so that by default only the user who submitted the job has permission to access the job outputs and the input data * *Is my approach correct? is it safe to use it this way?
