Hi
the SparkLauncher#setJavaHome method uses its argument to find the java
executable, but it does not reset the JAVA_HOME env var in the child
process. As a result, spark scripts such as bin/spark-class that rely on
JAVA_HOME use the wrong value. Adding this to setJavaHome fixes the problem:
builder.childEnv.put("JAVA_HOME", javaHome);
Should I submit a PR for this or if someone is already working on this code
maybe they can fix it?
