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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: common-issues-help@hadoop.apache.org
