Is Tez is part of cloudera versions?  If yes then how to use Tez for processing Hive quires?

It's not supported by Cloudera.

 

I've heard some users from the Hive community tried to make Tez work in Cloudera CDH, but it was hard to do it.

Hi,

 

I would like to understand why Tez is not supported in CDH?

 

Thanks,

I think "Tez" is not inhouse to CDH. "Tez" from other distrubution. It might take time for such support.

You are thinking of "He-Who-Cannot-Be-Named", aka Hortonworks. 8-)  Tez is a major selling point of their distribution.

Hi

I am a product manager at Cloudera working on SQL-on-Hadoop. I will answer your question regarding support for Tez in CDH.
 
Both Spark and Tez generalize the Mapreduce distributed computing framework that underlies many tools in the Hadoop ecosystem. At Cloudera, we believe that Spark is more suitable successor of Mapreduce because of its better architecture, more features, and a bigger community with ~100 contributors from ~25 companies. Hence, the support for Spark in CDH. Supporting Tez in addition to Spark in CDH would have added a lot of complexity to the platform while creating little value for our customers. Therefore, we decided not to support Tez in CDH.
