Probably the one tool missing from this list is Impala, which is essentially Hive's successor. Uses the same metastore and runs an order of magnitude faster. Almost the same flavor of SQL too.

Agree that Impala would fit well on this list. They didn't have any training on it, presumably because it's a Cloudera-led technology, but my understanding is it's very popular. Not sure that it truly replaces Hive/Tez though. I think they each excel at certain types of workloads.

Spark SQL does the same thing, slower than Impala (does not even have join reordering) but probably more popular.
