Hadoop “信息：Tez会议还没有建立。开幕式会议”挂起

我正在使用HDP2.3.0.0-2557，并尝试运行如下配置单元查询：

在接下来的比赛中，没有任何表现，而且似乎是特兹出了什么问题

此外，我尝试使用mapreduce而不是tez运行相同的查询，mapreduce作业挂起以及使用hive-hiveconf hive.execution.engine=mr启动hive CLI

我想知道是否有人能就如何解决这个问题提供一些建议

多谢

编辑1：我发现下面的链接，似乎没有足够的资源给tez。所以，我想知道如何清理被占用的资源，以便我有足够的资源给tez。

我也遇到了类似的问题。这可能是另一个阻止你的Tez会话运行的过程——在我的例子中，是Spark Thrift服务器阻止了它。监视ResourceManager节点上的内容Web UI默认端口为8088，请参阅页面底部。一旦旧货店的服务器被杀了，它就像一个魔咒一样运行着

我和你有同样的问题

我通过修改以下内容解决了这个问题

reduce-Tez-config:Tez.am.resource.memory.mb=256

默认值为2048

并增加纱线：为节点上的所有纱线容器分配的内存

我猜在HiveCLI上使用Tez需要{Tez.am.resource.memory.mb}内存。当{为节点上的所有纱线容器分配的内存}没有足够的内存时。然后应用程序id被挂起。
