> # Deployed cluster
> # Tried to delete host
> # Watch screenshot attached - Wizard says, that host cannot be deleted since it has the following master components :
> DRPC Server, Falcon Server, History Server, Metrics Collector, NameNode.
> # But, on background you can see, that there are such masters like Knox Gateway or Accumulo Master, for example. These masters have cardinality 1+ in metainfo.xml, but not mentioned in wizard and host can be deleted with them. (On cluster there was only 1 Knox Gateway and 1 Accumulo Master, on mentioned host)
