Hi, -- I am new to kafka and zookeeper. I have implemented my test environment with one Zookeeper node and 3 Kafka nodes. Now I want to increase my 1 zookeeper to 3 nodes ensemble.
-- I am continuously producing messages to one of the topic with python script while the msgs producing in progress I am trying to increase the nodes of zookeeper to 3 nodes from 1 node zookeeper. -- While increasing the standalone zookeeper to multi node I should restart the standalone zookeeper to know the new nodes existence to the standalone and take the leadership. -- When I restart standalone zookeeper there is minimum down time of zookeeper so the msgs which I am producing from python script are missing at the time of zookeeper restart. -- After the zookeeper 3 nodes is done I am trying to tell the kafka that there are another 2 nodes exists so again I should restart to update the new nodes in the kafka config file server.properties at that particular time also the msgs are lost. -- So is there any other procedure to update the Zookeeper and kafka configurations without loosing the Messages. -- I am trying to find the solution on Google but failed. Please help Regards, Srikanth
