thomasrebele opened a new pull request, #6036: URL: https://github.com/apache/hive/pull/6036
### What changes were proposed in this pull request? The TestVectorAggregation took 63s on my laptop due to a slow implementation of getLinearRandomNumber. I propose to replace the for loop with an analytical solution (HIVE-29155). With the patch, TestVectorAggregation takes only 23s. I've added javadoc to the method to make it easier to understand what the method is doing. I hope it is OK to remove some unused imports as well. ### Why are the changes needed? TestVectorAggregation is slower than necessary, therefore consuming resources (time & CPU) in the CI and machines of developers. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Manual test that the distribution of generated numbers stays the same. See attachment of HIVE-29155. TestVectorAggregation was executed and passes. -- This is an automated message from the Apache Git Service.
