ambari show datanode 4/5 after removing one datanode machine from the cluster

ambari show datanode 4/5 after removing one datanode machine from the cluster

hi all

 

 

we have 5 data node machine in the ambari cluster

 

we delete the last data node machine , ( from delete host )

 

and this process succeeded 

 

but from ambari dashboard  we still get Data node 4/6

 

instead to get 4/4

 

what else should be done in order to get the right new status ?
