How to set a custom JAVA_HOME when run flink on YARN?

[Renkai]

Hi,all:
  The YARN cluster of my company is default to use Java 7,and I want to use java 8 form my Flink application, whant can I do to achieve it?

[Renkai]

I think I solved myself,just add  -yD yarn.taskmanager.env.JAVA_HOME=xx in the command line, a little hard to find the solution though.

[Maximilian Michels]

Preferably, you set that directly in the config using

env.java.home: /path/to/java/home

If unset, Flink will use the $JAVA_HOME environment variable.

Cheers,
Max

It seems that this config variant only effect local cluster and stand alone cluster,not effect yarn.

The "env.java.home" variable is only evaluated by the start scripts, not the YARN code.

The solution you've mentioned earlier is a good work around in my opinion.
