Finally, it seems like I found the reason. It was a composition of several problems:
- Druid should not be built with maven 3.5.x. With 3.5.2, Test suites like `GroupByQueryRunnerFailureTest` fails. After I switched into 3.3.9 which is built in the latest version of IntelliJ, those errors disappeared. It seems like maven 3.5.x is not stable yet - it applied a drastic change, and it is also why they skipped 3.4.x. - It seems like Druid requires some MaxDirectMemorySize configuration for some test suites. With some JVM parameter like `-XX:MaxDirectMemorySize=4g` some test suites were passed, but not all. I am now trying the other options with enlarged swap space. Question: How much MaxDirectMemorySize configuration are you using? Best, Dongjin On Sat, Jul 21, 2018 at 3:01 AM Jihoon Son <ghoon...@gmail.com> wrote: > Hi Dongjin, > > that is weird.
