Review request for Ambari, Laszlo Puskas, Oliver Szabo, Sandor Magyari, and
Sebastian Toader.
Bugs: AMBARI-15862
https://issues.apache.org/jira/browse/AMBARI-15862
Repository: ambari
Description
-------
When deleting a host, NPE may occur.
TopologyHostRequests are created with hostName=null at the first time, and when
hosts are registered, then these null values are replaced with the correct host
names.
In the case when a host is being deleted, a loop checks the host name for all
the requests, and if there is a request with hostName=null, a NPE is thrown.
Swapping the sides of **equals** method can solve the problem, since the
variable **hostname** is checked before and not null.
