Hi -- Is there a way, by which a slave can get a trigger when a Hadoop jobs finished in master? The use case is as follows: I need to monitor the cpu, memory utilization utility automatically. For which, I need to know the timestamp to start and stop the sar utility corresponding to the start and finish of Hadoop job at master. Its simple to do at master, since the Hadoop job runs there, but how we do for slaves?
Thanks. Bikash
