Hi I am using solrCloud which uses an ensemble of 3 zookeeper instances.
I am performing survivability tests:
Taking one of the zookeeper instances down I would expect the client to use a
different zookeeper server instance.
But as you can see in the below logs attached
Depending on which instance I choose to take down (in my case, the last one in
the list of zookeeper servers)
the client is constantly insisting on the same zookeeper server (Attempting
connection to server zook3/192.168.252.78:2181)
and not switching to a different one
Any one has an idea on this ?
Solr cloud currently is using zookeeper-3.2.2.jar
Is this a know bug that was fixed in later versions ?( 3.3.1)
Thanks in advance,
Yatir
