             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.
