Hadoop Hbase区域服务器关闭

我是Mohanselvakumar，是Hbase系统的新手，请求在以下方面为我的一台Hbase服务器提供帮助

场景是，我已经设置了10个节点的集群，其中有2个名称节点（一个主节点和一个辅助节点）

在10个节点上，我在所有节点上运行Datanode和Regionserver服务

现在问题出在10个节点中，其中一个节点由于以下异常而持续下降

Zookeeper过期可能是由于节点内存不足、GCs过长等原因造成的。请参阅第12.9.2.7节

您可以像这样在hbase-site.xml中添加会话超时

      <property>
        <name>zookeeper.session.timeout</name>
        <value>60000</value>
      </property>

zookeeper.session.timeout
60000

      <property>
        <name>zookeeper.session.timeout</name>
        <value>60000</value>
