#560 Agree, it's a more throughout way to handle this issue. In the code
you have, it seems that the spark jar setting is moved to conf: SparkConf in
favor of the CONF_SPARK_JAR. But it will make users difficult to set it up
since the Client.scala also has to be changed. Simple question, with your
change, how users can submit job with their own spark jar by passing the
CONF_SPARK_JAR correctly?
def sparkJar(conf: SparkConf) = {
if (conf.contains(CONF_SPARK_JAR)) {
conf.get(CONF_SPARK_JAR)
} else if (System.getenv(ENV_SPARK_JAR) != null) {
logWarning(
s"$ENV_SPARK_JAR detected in the system environment. This
variable has been deprecated "
s"in favor of the $CONF_SPARK_JAR configuration variable.")
System.getenv(ENV_SPARK_JAR)
} else {
SparkContext.jarOfClass(this.getClass).head
}
}
