But in standalone mode, should the safemode be faster? I mean because everything is running locally. still the deamons are not visible in jps. how can i restart it individually?
also, the service status returned this info: Hadoop namenode is running [ OK ] Hadoop secondarynamenode is not running [FAILED] Is the secondary namenode, not supposed to run in standalone mode? i am not able to restart this service also.. it just gives unrecognized service.
