["Marcelo Vanzin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-22414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16234775#comment-16234775 ] 

Marcelo Vanzin commented on SPARK-22414:
----------------------------------------

Have you tried {{spark.yarn.appMasterEnv.FOO}}? Pretty sure that's used for the AM in both client and cluster (= driver) mode.

> We're trying to upgrade to 2.2.0 from 2.1.0 at Twitter but it seems that there's no way to set the JAVA_HOME for the driver running on the yarn am.
> https://issues.apache.org/jira/browse/SPARK-17979 removed the environment variable SPARK_YARN_USER_ENV, but provided no alternative to set env variables for the driver since `spark.executorEnv` is only for executors.
