Also the code in tear down is commented out. +ListTTClient ttClients = cluster.getTTClients(); + +//One slave is got +TTClient ttClient = (TTClient)ttClients.get(0); I have a similar helper method, that I will check in AbstractDaemonCluster with health script, it is better to use that helper, I will check in this code shortly. //The client shich needs tobe decommissioned is put in the exclude path. Fix the typo in the comment. One question is you were telling me that hadoopqa user is executing mradmin refresh which requires mapred priviledge, so how is this achieved wiith this code. If this is going to be deployment specific changes to mapred-site.xml we should call out that dependency, so it is actionable.
