Im wondering did someone every try to delete a host and then readd? I kind of cilled one host and tried to readd it after a complete reinstall of linux. Unfortunately the hostname is still the same due company network restrictions. Trying to add the host again i recognized that ambari doesnt really delete the host. There must be some data left since sometimes i still see the old amount of hosts and it sometimes even pop ups in the host list with 0 Components.
Since my cluster is pretty new i think ill just reinstall ambari completely but still im wondering why cant i just delete a host properly? i restarted ambari and the server node multiple times but he still got some data left from the old host…
