Hi, We are in process of exploring TEZ for Hive 0.14. Needed some pointers to start on Hive with Tez. E.g. in Hive HDFS Block size plays a vital role in getting the number of Mappers and later independent execution of mappers can accelerate processing substantially.
I understand this is a very vast topic and cannot be described, however some quick pointers will be helpful. I am currently working on: Query vectorization and COB with ORC tables. Thanks, Saurabh
