Aniket Bhatnagar commented on SPARK-1350:
-----------------------------------------
I am using hadoop 2.5.0 (CDH). Agreed that it handles for windows. But the use
case I am talking about is when SparkContext is created programmatically on a
windows machine and is used to submit jobs on a yarn cluster running on Linux.
As per above code, %JAVA_HOME%/bin/java will be generated as one of the
commands by ClientBase and submitted to YARN cluster. This will obviously fail
while YARN tries to execute the container as % is treated differently in linux.
> YARN ContainerLaunchContext should use cluster's JAVA_HOME

> 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.
