Tev map engine is faster ... but...

What do you like best?

Speed is the number one thing I found to be most important. I found it having much better improvement over MR.

What do you dislike?

Sometimes I found if I used Tez on Hive queries on certain S3 backed tables using a standard serde like 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe' or 'com.bizo.hive.serde.csv.CSVSerde' I would receive Hadoop error. I changed to MapReduce execution engine and it would work. Not sure why this happens.

Recommendations to others considering the product:

Tez does improved Hive queries considerably

What problems are you solving with the product? What benefits have you realized?

Improve overall performance of Hive queries.
