You are looking at vastly different technologies.

Hive is batch processing system with an SQL frontend. At best it works at
analytic speed. Queries over GB of data in the seconds to minute range.

This is different then single node "in memory" databases. (HSQL)

Which are different then multi-node distributed in memory databases (VoltDB)

Aerospike and redis are KV like stores without relational capabilities.
