Yes as an example of running a mapreduce job followed by a tez you can see our last post on this https://blogs.apache.org/bigtop/entry/testing_apache_tez_with_apache . You can see in the bigtop/tez testing blogpost that you can confirm that Tez is being used easily on the web ui.
>From TezClent.java: /** * TezClient is used to submit Tez DAGs for execution. DAG's are executed via a * Tez App Master. TezClient can run the App Master in session or non-session * mode. <br> * In non-session mode, each DAG is executed in a different App Master that * exits after the DAG execution completes. <br> * In session mode, the TezClient creates a single instance of the App Master * and all DAG's are submitted to the same App Master.<br> * Session mode may give better performance when a series of DAGs need to * executed because it enables resource re-use across those DAGs. Non-session * mode should be used when the user wants to submit a single DAG or wants to * disconnect from the cluster after submitting a set of unrelated DAGs. <br> * If API recommendations are followed, then the choice of running in session or * non-session mode is transparent to writing the application. By changing the * session mode configuration, the same application can be running in session or * non-session mode. */ On Mon, Sep 1, 2014 at 12:43 PM, Alexander Pivovarov <apivova...@gmail.com> wrote: > e.g. in hive to switch engines > set hive.execution.engine=mr; > or > set hive.execution.engine=tez; > > tez is faster especially on complex queries. > On Aug 31, 2014 10:33 PM, "Adaryl "Bob" Wakefield, MBA" < > adaryl.wakefi...@hotmail.com> wrote: > >> Can Tez and MapReduce live together and get along in the same cluster? >> B. >> > -- jay vyas
