How to configure java home on flink job on yarn

Question

I submit a job to the hadoop cluster on the flink client, do I need to configure the java home path in flink conf?

If you need to configure，

Should I configure the java home of the client machine or the java home of the hadoop cluster？

When I did not configure java home, I submitted the job error as follows

Answer 1

According the output you posted, you problem is not java_path (yet!) The line

Unrecognized VM option 'MaxMetaspaceSize=268435456'

You need to remove MaxMetaspaceSize from configuration or replace it with: -XX:MaxMetaspaceSize

you can get help from this issue.
