一、产生背景
2.1 DAG
2.2 Runtime API——Input/Processor/Output
2.3 Runtime优化
2.4 其他优化措施
三、优缺点
四、Hive On Tez：
•MR性能差，资源消耗大，如：Hive作业之间的数据不是直接流动的，而是借助HDFS作为共享 …
•MR 默认了map和reduce阶段，map会对中间结果进行分区、排序，reduce会进行合并排序，这一过程并不适用于所有场景。

Apache Tez 是什么? - InfoQ
Tez 是 Apache 最新的支持 DAG 作业的开源计算框架，它可以将多个有依赖的作业转换为一个作业从而大幅提升 DAG 作业的性能。Tez 并不直接面向最终用户——事实上它允许开发者为最终用户构建性能更快、扩展性更好的应用程序。

What is Tez in hive?
In conjunction with Hive 0.14’s Cost Based Optimizer, Tez enables the execution of bushy join plans which can take advantage of in-termediate broadcast joins. The pluggable task model of Tez allows Hive to use custom vectorized operators throughout the processing. Custom edges are used to perform efficient Hive sort-merge-bucket joins.

What makes Tez different?
Tez allows out of order execu-tion for performance reasons and has built-in preemption to resolve scheduling deadlocks. Overall, Tez differs from these systems in its modeling capabilities and the design goal of being a library to build engines rather than being an engine by itself.

Is Tez a security threat?
Security is a real concern with the variety of data stored and concurrent access from multiple users. Being outside the data plane reduces the contribution of Tez in the threat surface of the application. The only interaction between Tez and the app is control metadata routed via events by Tez.

How does Tez work?
Tez monitors task progress and tries to detect straggler tasks that may be running much slower than other tasks in the same vertex. Upon detecting such a task, a specu-lative attempt may be launched that runs in parallel with the original task and races it to completion.

Is Tez a general purpose engine?
Tez, again differs being a library and not a general purpose engine. Tez does not provide any storage service but applications can use existing in-memory stores, e.g. HDFS memory storage , to get the advan-tage of in-memory computing.

How does Tez define a task?
Tez defines each task as a composition of a set of inputs, a processor and a set of outputs (IPO). The processor is defined by the vertex for that task. The inputs are defined by the output classes of the incoming edges to that vertex. The outputs by the input classes of the outgoing edges from that vertex.
