Subject Re: delete using API problem
Date Fri, 17 Apr 2015 17:53:51 GMT
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.
