Hi there, I am trying to introduce some sort of security to prevent different people using the cluster from interfering with each other's jobs.
Following the instructions at http://hadoop.apache.org/docs/stable/cluster_setup.html and https://www.inkling.com/read/hadoop-definitive-guide-tom-white-3rd/chapter-9/security , this is what I put in my mapred-site.xml: <property> <name>mapred.task.tracker.task-controller</name> <value>org.apache.hadoop.mapred.LinuxTaskController</value> </property> <property> <name>mapred.acls.enabled</name> <value>true</value> </property> I can see the configuration parameters in the job configuration when I run a hive query, but the users are still able to kill each other's jobs. Any ideas about what I may be missing? Any alternative approaches I can adopt? Thanks.
