Introduction

In our previous article, we evaluated the performance of Hive 4 on MR3 1.11 and Trino 453 on the 10TB TPC-DS benchmark. The results can be summarized as follows:

  • In terms of the total running time, Hive 4 on MR3 runs slightly faster than Trino -- Hive 4 on MR3 5744 seconds vs Trino 5798 seconds.
  • In terms of the geometric mean of running times, Trino responds about 15 percent faster than Hive 4 on MR3 -- Trino 17.99 seconds vs Hive 4 on MR3 21.02 seconds.

Hive Performance: Hive-LLAP in HDP 3.1.4 vs Hive 3/4 on MR3 0.10

Introduction

In our previous article published in October 2018, we use the TPC-DS benchmark to compare the performance of Hive-LLAP in HDP 3.0.1 (as well as HDP 2.6.4) and Hive 3 on MR3 0.4. We have shown that Hive 3 on MR3 yields consistently higher throughput than Hive-LLAP in concurrency tests, but since then, the performance of Hive-LLAP has improved considerably for concurrent queries. Thus we are interested in the question of how Hive on MR3 compares with Hive-LLAP in the latest lease of HDP.
