 **@ravi.maddi:** ** I am starting pinot components, as first step I am trying
to start zookeeper. I am running the command to start zookeeper: ```bin/pinot-
admin.sh StartZookeeper -zkPort 2181``` But I am getting like this after some
time: ```zookeeper state changed (SyncConnected) Waiting for keeper state
SyncConnected Terminate ZkClient event thread. Session: 0x1000014c3150000

suggestions prescribed online. Even no luck. Need help :slightly_smiling_face:  
**@mayanks:** Do you have a server session running from previous run? I have
seen this error when the previous server run is interacting with newly
launched ZK
