hadoop - “INFO : Tez session hasn'还没有创建。开幕式”挂起

我正在使用HDP 2.3.0.0-2557，并且尝试运行类似以下内容的配置单元查询:

INFO  : Tez session hasn't been created yet. Opening session

事后，没有任何显示，而且“Tez”似乎有问题

另外，我尝试使用“mapreduce”而不是“tez”运行相同的查询，并且mapreduce作业也挂起(使用hive -hiveconf hive.execution.engine=mr启动hive CLI

hive> select max(IT1C1+IT1C2) from iitest1;

我想知道是否有人可以提供有关如何解决该问题的指导？

非常感谢!

编辑1:我发现以下link并基于链接，看来没有足够的资源用于tez。因此，我想知道如何清除已占用的资源，以便有足够的资源用于tez。

最佳答案

我有类似的问题。这可能是另一个阻止您的Tez session 运行的进程-就我而言，正是Spark Thrift Server阻止了它。监视ResourceManager节点上的内容(Web UI的默认端口为8088，请参见here页的底部)。 Thrift Servers被杀死后，它就像魅力一样运行!
