I am using ES 6.8 in a docker container.
Now, this docker images is using Java 12, and this is causing some bad reports from our security department.
Seems only approved versions are LTS ones. I think i want to change it to Java 11
So my question is :
How can i change the Java version inside the container/image ?
Second question is:
Can i change the version one by one? This will result cluster with different java version at at a time.
Or do i need to shut-down the whole cluster ?
Thank you in advance
