(hive on Tez)Caused by: org.apache.tez.dag.api.SessionNotRunning: TezSession has already shutdown.

hive on Tez :TezSession has already shutdown.

在hive里面配置Tez，配置完启动hive的时候hive启动不起来了，报了这样的错：

经过一番度娘的帮助，终于找到了相关博客！！自己也记录一下，免得下次一样找半天！

这种问题是从机上运行的Container试图使用过多的内存，而被NodeManager kill掉了。

关掉虚拟内存检查,修改yarn-site.xml文件（添加相关代码）！！

cd /opt/module/hadoop/etc/hadoop
vim yarn-site.xml

关掉虚拟机内存检查！！

        yarn.nodemanager.vmem-check-enabled
        false

发给其他所有节点，重启yarn服务！

其实改掉这个再重启hive就可以成功了的，但我犯了一个愚蠢的错误，那就是我的主机是hadoop101,但我的资源分配由Hadoop102负责，我只修改了Hadoop101里面的配置文件，没修改102里面的，所以还是报了一样的错，最终我把这个修改过的yarn-site.xml文件发给了其他所有的节点，重启了yarn 服务，可以了！！

这是我找到的另外一篇博客，里面还有一种方法！
