we have ambari cluster , version 2.6.x , with 3 kafka machine and 3 zookeper servers
while kafka machines are not chosted with zookeper server ( kafka are on different machines )
in order to get the brokers id , we do the following on the zookeper servers
results should be the three brokers id's as
1011 1012 1013
my question is - in which way zookeper know that broker is up?
or to be more specific
which cli zookeper execute in order to identify that kafka broker is up ?
