Apache zookeeper Zookeeper EndOfStreamException发生在Heron群集中

apache-zookeeper

Apache zookeeper Zookeeper EndOfStreamException发生在Heron群集中,apache-zookeeper,heron,Apache Zookeeper,Heron,有一个问题困扰着我。EndOfStreamExceptionalways在提交拓扑后在zookeeper中发生。虽然它不会影响集群的正常运行，但我还是希望能够解决这个问题，因为它可能会影响Heron函数的其他部分。 zookeeper版本是3.4.10，部署在集群中一个主机的standalonemode上。zoo.cfg的内容如下 tickTime=10000 initLimit=100 syncLimit=50 dataDir=/home/yitian/zookeeper/data dataL

有一个问题困扰着我。EndOfStreamExceptionalways在提交拓扑后在zookeeper中发生。虽然它不会影响集群的正常运行，但我还是希望能够解决这个问题，因为它可能会影响Heron函数的其他部分。 zookeeper版本是3.4.10，部署在集群中一个主机的standalonemode上。zoo.cfg的内容如下

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

此外，dataDir中还有myidfile，其内容为：1。这是我的zookeeper配置。 heron中statemgr.yaml的内容如下：

com.twitter.heron.statemgr.zookeeper.curator.CuratorStateManager

heron.statemgr.root.path:                       "/heron"
