[jira] [Created] (HDFS-10370) Allow DataNode to be started with numactl

Dave Marion created HDFS-10370:
----------------------------------

             Summary: Allow DataNode to be started with numactl
                 Key: HDFS-10370
                 URL: https://issues.apache.org/jira/browse/HDFS-10370
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: datanode
            Reporter: Dave Marion


Allow numactl constraints to be applied to the datanode process. The implementation I have in mind involves two environment variables (enable and parameters) in the datanode startup process. Basically, if enabled and numactl exists on the system, then start the java process using it. Provide a default set of parameters, and allow the user to override the default. Wiring this up for the non-jsvc use case seems straightforward. Not sure how this can be supported using jsvc.
