查看錯誤日志

不一定能在 Client日志 里面看到錯誤，可以打開AM的WEB頁面查看：

也可以調(diào)整opts和memory兩個配置。

修改配置

[eshore@bigdatamgr1 ~]$ cat hadoop/etc/hadoop/yarn-site.xml 
...
<property>
  <name>yarn.nodemanager.vmem-check-enabled</name>
  <value>false</value>
  <description>Whether virtual memory limits will be enforced for containers</description>
</property>
<property>
  <name>yarn.nodemanager.vmem-pmem-ratio</name>
  <value>4</value>
  <description>Ratio between virtual memory to physical memory when setting memory limits for containers</description>
</property>

同步到所有nodemanager，然后重啟yarn。
