Is it possible to set the custom JVM Options env.java.opts when submitting a job without specifying it in the conf/flink-conf.yaml file?
The reason I am asking is I want to use some custom variables in my log4j. I am also running my job on YARN.
I have tried the following command using the CLI and it strips everything off from the = sign onwards
$ flink run -m yarn-cluster -yn 2 -yst -yD env.java.opts="-DappName=myapp -DcId=mycId"
回答1:
At the moment this is not possible due to the way Flink parses the dynamic properties. Flink assumes that dynamic properties have the form -D<KEY>=<VALUE> and that <VALUE> does not contain any = which is clearly wrong. Thus, for the moment you have to specify the env.java.opts via flink-conf.yaml.
I've opened a JIRA issue to fix this problem.
