Introduction​

Recently Apache Hive 4 was released after a hiatus of several years. We have released Hive 4 on MR3 which replaces Tez with MR3 as the default execution engine in Hive 4.

Introduction​

In our previous article, we evaluate the performance of Trino 418 and Hive on MR3 1.7 using the TPC-DS Benchmark with a scale factor of 10TB.

• In terms of the total running time, the two systems are comparable: Trino 7424 seconds vs Hive on MR3 7415 seconds.
• In terms of the geometric mean of running times, Trino is faster than Hive on MR3: Trino 21.75 seconds vs Hive on MR3 27.68 seconds.
• Trino returns wrong answers on query 23 after running for 1756 seconds.
• Trino fails to complete query 72 after running for 156 seconds.

Introduction​

Before MR3 1.8, Hive on MR3 was built with Java 8. From MR3 1.8, we release Hive on MR3 built with Java 17 as well. An immediate benefit of upgrading to Java 17 is a significant improvement in speed and stability.

Introduction​

In this article, we evaluate the performance of the following systems.

1. Trino 418 (released on May 17, 2023)
2. Spark 3.4.0 (released on Apr 13, 2023)
3. Hive 3.1.3 on MR3 1.7 (released on May 15, 2023)

Introduction​

In this article, we evaluate the performance of the following systems.

1. Spark 2.3.8
2. Spark 3.2.1
3. Hive 3.1.2 on MR3 1.4
4. Hive-LLAP in HDP 3.1.4 (3.1.0.3.1.4.0-315)

Hive and Presto​

Hive and Presto have developed a tortoise-and-hare story over the past 8 years. Initially conceived at Facebook and open sourced in August 2008, Hive was hailed as a breakthrough in the SQL-on-Hadoop technology and generally regarded as the de facto standard. Then in 2012, Facebook started to develop Presto as a replacement of Hive, which was considered too slow for their daily workload. As Facebook was specific about its goal in developing Presto, the future of Hive did not look so bright.

Introduction​

In our previous article published in October 2018, we use the TPC-DS benchmark to compare the performance of Hive-LLAP and SparkSQL 2.3.1 included in HDP 3.0.1 along with Hive 3.1.0 on MR3 0.4. In this article, we update the result by testing SparkSQL 2.3.2 included in HDP 3.1.4. As in the previous experiment, we use the TPC-DS benchmark.

Introduction​

In our previous article, we use the TPC-DS benchmark to compare the performance of three SQL-on-Hadoop systems: Impala 2.12.0+cdh5.15.2+0, Presto 0.217, and Hive 3.1.1 on MR3 0.6. It uses sequential tests to draw the following conclusion:

• Impala runs faster than Hive on MR3 on short-running queries that take less than 10 seconds.
• For long-running queries, Hive on MR3 runs slightly faster than Impala.
• For most queries, Hive on MR3 runs faster than Presto, sometimes an order of magnitude faster.

Introduction​

Do you trust Hive? Do you trust Presto? Do you trust Impala? Do you trust your SQL system?
