Apache Pinot

I’m going to merge java 11 upgrade PR(<https://github.com/apache/incubator-pinot/pull/6424|#6424>) today, for devs still on java8, please use
```mvn clean install -DskipTests -Pbin-dist -T 4  -Djdk.version=8```
to build pinot source code.

Does it make sense to have a flag for java 11 instead? I am thinking code that links with the segment build logic -- may not get to choose their own java RTE. This is certainly the case with Linkedin. Are there others in a similar situation?

that’s why  we would like to call it out now and say we still support java 8 until next release

then we will drop java8 support and have people use java11

otherwise we will never get to upgrade :stuck_out_tongue:
