Description

we know that jdk11 is a LTS version, but the technical support will be end in September 2023. JDK17 is the next generation LTS version, and will support a least to 2026.

for G1GC, Java17 will get 8.66% faster than Java11, for ParallelGC, the percent will be 6.54%. If we upgrade to java17, we will get more performance improvementthan Java11.

I suggest, we upgrade hive version to support java17.
