hive on tez執行任務報錯，did not succeed due to VERTEX_FAILURE

hive on tez，在執行任務的時候報錯，這種情況原因是container資源被搶佔或者是資源不足。而task最大的失敗次數默認是4.

解決方案：
1、am自己失敗的最大重試次數，默認是2次。這裏並不是說am自己掛了，只是因爲一些系統原因導致失聯了，命令行直接設置

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

如果解決了問題的話可以把它配置到配置文件(tez-site.xml)中
2、還有一個原因我認爲container設置的內存太小，我本來是1G，改爲4G後沒啥問題了。
在hive-site.xml中，加入以下配置

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