There is a problem that bothers me. EndOfStreamExceptionalways happen in zookeeper after submitted topologies. Although it does not affect the normal operation of the cluster, I still hope to solve the problem because it may be affect other parts of Heron function. The zookeeper version is 3.4.10 and was deployed on standalonemode in one host of my cluster. The contents of zoo.cfg are as follows.
tickTime=10000
initLimit=100
syncLimit=50
dataDir=/home/yitian/zookeeper/data
dataLogDir=/home/yitian/zookeeper/logs
clientPort=2181
maxClientCnxns=100
server.1=heron01:2888:3888
Moreover, there is the myidfile in dataDir, and its content is: 1. That is my configuration of zookeeper. The contents of the statemgr.yaml in heron are as follows:
com.twitter.heron.statemgr.zookeeper.curator.CuratorStateManager
heron.statemgr.connection.string: "heron01:2181"
heron.statemgr.root.path: "/heron"
heron.statemgr.zookeeper.is.initialize.tree: True
There are four hosts in my Heron cluster, one mesos master host and three agent hosts. And in zookeeper log files, EndOfStreamException occurred in the three agent hosts. The contents of zookeeper.log are as follows:

In above zookeeper.log, the host with IP:218.195.228.24 is the master node, hosts list with IP: 28, 19, 43 are agents nodes. I have tried a lot of methods, but they don't work. What is the cause of the problem? And how can I fix it? Thanks a lot for your help.
回答1:
Yitan - If you are using in Aurora and during submission, the client directly writes into the zookeeper the logical plan. It might be possible the zookeeper client running on heron client might not be gracefully terminating.
回答2:
Issue seems to be at client side as per below ZK issue: https://issues.apache.org/jira/browse/ZOOKEEPER-1582
You may have to check the logs of the Zookeeper client trying to connect.
