Cluster :

3 Zookeeper quorum

2 Kafka Replica

Samza Job managed by Yarn

I see this exception periodically on our zookeeper logs :

EndOfStreamException: Unable to read additional data from client sessionid 0x0, likely client has closed socket

at org.apache.zookeeper.server.NIOServerCnxn.doIO(NIOServerCnxn.java:230)

at org.apache.zookeeper.server.NIOServerCnxnFactory.run(NIOServerCnxnFactory.java:203)

at java.lang.Thread.run(Thread.java:745)

I have checked this Jira ticket, but nothing substantial on how to solve it.

Also I have configured zookeeper to Autopurge transactional logs and the snapshots.

Here is my config :

clientPort=2181

dataDir=/opt/zookeeper

tickTime=2000

initLimit=5

syncLimit=2

autopurge.snapRetainCount=3

autopurge.purgeInterval=1

server.1=server1:2888:3888

server.2=server2:2888:3888

server.3=server3:2888:3888

Want to understand what this is actually saying, and how to resolve it.

Thanks
