'• 10-15 years of working experience with 3+ years of experience as Big Data solutions architect. Before comparison, we will also discuss the introduction of both these technologies. Each cluster should be created in the US East EC2 Region, For Hive and Tez, use the following instructions to launch a cluster. Our benchmark results indicate that both Impala and Spark SQL perform very well on the AtScale Adaptive Cache, effectively returning query results on our 6 Billion row data set with query response times ranging from from under 300 milliseconds to several seconds. Consider Impala We had had good experiences with it some time ago (years ago) in a different context and tried it for that reason.
