Hi Jun,
There is no ZK session timeout on the broker. I did increase ZK session timeout
from 6000 ms to 10000ms. It is weird. Some times I get Connection timed out and
some times EOF exception.
When those occur I see hung socket/sockets "send-q" by running command netstat:
in the below example 195480 bytes would be there until errors out. Some times
after 2-3 minutes those would clear and everything would written to topic
partitions.
tcp 0 0 ourhost:56155 kafkaserver21:XmlIpcRegSvc ESTABLISHED
tcp 0 0 ourhost:56169 kafkaserver21:XmlIpcRegSvc ESTABLISHED
