[jira] [Created] (KYLIN-3810) kylin

zhangwei created KYLIN-3810:
-------------------------------

             Summary: kylin 
                 Key: KYLIN-3810
                 URL: https://issues.apache.org/jira/browse/KYLIN-3810
             Project: Kylin
          Issue Type: Improvement
          Components: Metadata, Others
    Affects Versions: v2.6.0, v2.5.0
            Reporter: zhangwei
             Fix For: v2.5.1


由于Kylin的元数据同步使用了Boardcast类中的线程池，所以一旦负载均衡查询节点中一台机器岩机，Kylin的同步请求线程会堵塞在岩机的查询节点，最后将线程资源全部占满，如图同步到1,2节点的请求堵塞在线程队列中导致查询节点获取不到最新元数据从而无法查询到实时构建好的数据

我们的方案:
引进了服务发现组建zookeeper
