> Key: HIVE-17573
> URL: https://issues.apache.org/jira/browse/HIVE-17573
> Project: Hive
> Issue Type: Bug
> Components: llap
> Affects Versions: 3.0.0
> Reporter: Gopal V
> Assignee: Gopal V
> Priority: Major
>
> The perf diff between JDK8 -> JDK9 seems to be significant.
> TPC-H Q6 on JDK8 takes 32s on a single node + 1 Tb scale warehouse.
> TPC-H Q6 on JDK9 takes 19s on the same host + same data.
> The performance difference seems to come from better JIT and better NUMA
> handling.
