Overwrite environment variables in single-job deployment on YARN

Mariusz Wojakowski
Hi,

I want to run Flink job on YARN and I need to overwrite JAVA_HOME on Task Managers. In multi-job mode I can do it by passing parameter when starting cluster: 

./yarn-session.sh -D yarn.taskamanager.env.JAVA_HOME=“/opt/jre1.8.0”

I want to overwrite this variable in single-job deployment, but it doesn’t work - TM’s JAVA_HOME is unchanged.
Maybe I’m missing something - could you give me some advice how to do that?


Thanks!
Mariusz

Hi,

Have you tried 

./bin/flink run -m yarn-cluster -yD yarn.taskmanager.env.JAVA_HOME=“/opt/jre1.8.0”

-yD can be used to dynamically specify settings.

Best,

Thanks! It works :)

I’ve tried that but I’ve also misspelled ’taskmanager’… 

Sorry & thanks one more time!
