hive集群tez引擎执行任务卡住_tez任务不终止

更换tez引擎后，如果执行任务卡住，修改调节容量调度器的资源调度策略，修改以下配置信息

cd /opt/module/hadoop-3.1.3/etc/hadoop/ 
vim tez-site.xml

<!--容器给AM分配的资源-->
 <property>
      <name>tez.am.resource.memory.mb</name>
      <value>1024</value>
 </property>
 <property>
      <name>tez.am.resource.cpu.vcores</name>
      <value>1</value>
 </property>
 <!--堆占整个资源的占比 -->
 <property>
      <name>tez.container.max.java.heap.fraction</name>
      <value>0.4</value>
 </property>
 <!--容器给task分配的资源 -->
 <property>
      <name>tez.task.resource.memory.mb</name>
      <value>1024</value>
 </property>
 <property>
      <name>tez.task.resource.cpu.vcores</name>

vim capacity-scheduler.xml

将以下value调成1

 <!--AM所占集群最大资源占比-->
   <property>
     <name>yarn.scheduler.capacity.maximum-am-resource-percent</name>
     <value>1</value>
     <description>
       Maximum percent of resources in the cluster which can be used to run 
       application masters i.e. controls number of concurrent running
       applications.
     </description>
   </property>

向集群分发capacity-scheduler.xml文件。
