I am seeing a lot of these: 17 Apr 2015 13:52:18,828 WARN [pool-2-thread-684] RestMetricsPropertyProvider:204 - Unable to get component REST metrics. No host name for STORM_UI_SERVER. 17 Apr 2015 13:52:25,183 WARN [pool-2-thread-685] RestMetricsPropertyProvider:204 - Unable to get component REST metrics. No host name for STORM_UI_SERVER. 17 Apr 2015 13:52:31,615 WARN [pool-2-thread-678] RestMetricsPropertyProvider:204 - Unable to get component REST metrics. No host name for STORM_UI_SERVER.
I must confess that I erased all storm packages from each server prior to doing any API calls, if that is of any help.
