I'm new to Hadoop and I'm trying to do something I *think* should be easy but having some trouble. Here's the details.
1. I'm running Hadoop version 1.0.2
2. I have a 2 Node Hadoop Cluster up and running, with no security enabled
I'm having trouble overriding the username from the client so that the files/directories created are owned by the user I specify from the client.
For example I'm trying to run:
hadoop fs -Duser.name=someUserName -conf hadoop-cluster.xml -mkdir /user/someOtherUserName/test
And have the directory "test" created in hdfs and owned by "someUserName". Instead it is creating the directory and giving it the owner of the user (whoami) from the client. I'd like to override or control that…can someone tell me how?
My hadoop-cluster.xml file on the client looks like this:
Thanks for the help
