How can I pass multiple java options in standalone mode ?

[Vishwas Siravara]

Hi guys,

I have this entry in flink-conf.yaml file for jvm options. 

env.java.opts: "-Djava.security.auth.login.config={{ flink_installed_dir }}/kafka-jaas.conf,-Djava.security.krb5.conf={{ flink_installed_dir }}/krb5.conf"

Is this supposed to be a , separated list ? I get a parse exception when the cluster starts. 

Thanks,

Vishwas

Hi Vishwas,

Replace ',' with ' '(space) should work.

When I add env.java.opts like this

 env.java.opts:"-Dconfig.resource=qa.conf"

I see an error in the log file saying :  - Error while trying to split key and value in configuration file /data/flink-1.7.2/conf/flink-conf.yaml:248: "env.java.opts:"-Dconfig.resource=qa.conf""

This is really confusing and I cant find any document on how I should pass this option. 

Thanks,

It’s a YAML file, so I think you need to do something like

 env.java.opts: -Dconfig.resource=qa.conf

Thanks a lot, I fixed that, so now this works when I submit my job with the flink UI but when I submit it via flink run(command line) it does not take this env.java.opts: -Dconfig.resource=qa.conf property . How can I pass the jvm property to flink run which is running standalone without resource manager.

Hi Vishwas

The java option is used to start jobmanager and taskmanager jvm process. It should take effect when you set is in the flink-conf.yaml on all nodes. 

It is a flink cluster level configuration, not a job level. So i'm not sure what do you want to do.

Yang

No this does not work , the config in flink-config.yaml applies only to job manager and task manager for env.java.options. When I say "flink run ..." from command line, there is a new jvm which is created which starts the main method and that does not get the env.java.options which is set in the flink-conf.yaml. This works when I set JVM_ARGS and export it before "flink run ..."

Hi Vishwas,

I think we are on the same page now.

> When you submit a job through Flink WebUI, your main code will be executed in the job manager jvm process. Since job manager is started with the java opts in flink-conf.yaml, so you could find it works.

> When you submit a job in command line(flink run), your main code will be executed in flink client jvm process. The flink client does not parse the config option(env.java.options) in flink-conf.yaml, so you need to export the JVM_ARGS environment so that the flink script could append it to java command.[1]

Just to make clear that env.java.options only applies to jobmanager and taskmanager jvm processes.
