----------------------------------
Summary: Upgrade to Java17
Key: HIVE-26473
URL: https://issues.apache.org/jira/browse/HIVE-26473
Project: Hive
Issue Type: Improvement
Reporter: dingwei2019
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.
