>                 Key: SPARK-1350
>                 URL: https://issues.apache.org/jira/browse/SPARK-1350
>             Project: Spark
>          Issue Type: Bug
>          Components: YARN
>    Affects Versions: 0.9.0
>            Reporter: Sandy Ryza
>            Assignee: Sandy Ryza
>             Fix For: 1.0.0

> {code}
>     var javaCommand = "java"
>     val javaHome = System.getenv("JAVA_HOME")
>     if ((javaHome != null && !javaHome.isEmpty()) || env.isDefinedAt("JAVA_HOME"))
{
>       javaCommand = Environment.JAVA_HOME.$() + "/bin/java"
>     }
> {code}
> Currently, if JAVA_HOME is specified on the client, it will be used instead of the value
given on the cluster.  This makes it so that Java must be installed in the same place on the
client as on the cluster.
> This is a possibly incompatible change that we should get in before 1.0.
