Tez is not available in CDH 5. We generally prefer (and test) Spark and Impala over Tez.
We would need to research and test if all current hive code is supported by impala, and we are doing a migration POC
Thanks a lots for your quick response
Tez will run just fine on CDH5. Tez has been built against a Hadoop 2.2 foundation (requires a Hadoop >= 2.2 with a running YARN service, not MRV1). This is the default setup for CDH5. Any application can itself deploy/use Tez with zero install/config required by the customer.
That said, Cloudera is not actively supporting / contributing to Tez development, so it is solely the responsibility of gthe application vendor to support Tez compontents on CDH. We at Datameer fully support the Tez stack on CDH5 as a component of our YARN application.
So, To summarize, Cloudera CDH 5.1.3 does not not support Hive on Tez. As Tez is available only on Apaache Hive 0.13 and over. Cloudera CDH 5.1.3 is only apache hive 0.12. Correct me if the summarization is wrong
This post is from 4 years ago. I wonder if now (2018) anything has change and now cloudera can support Hive on Tez... Can you please advise... If not what would be my other alternatives?.... Thanks..
