hive on tez执行任务报错，did not succeed due to VERTEX_FAILURE

hive on tez，在执行任务的时候报错，这种情况原因是container资源被抢占或者是资源不足。而task最大的失败次数默认是4.

解决方案：
1、am自己失败的最大重试次数，默认是2次。这里并不是说am自己挂了，只是因为一些系统原因导致失联了，命令行直接设置

set tez.am.max.app.attempts=5

如果解决了问题的话可以把它配置到配置文件(tez-site.xml)中
2、还有一个原因我认为container设置的内存太小，我本来是1G，改为4G后没啥问题了。
在hive-site.xml中，加入以下配置

<property>
    <name>hive.tez.container.size</name>
    <value>4096</value>
</property>
