------------------------------
Summary: LLAP: JDK9 support fixes
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
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.
