> SPARK_DAEMON_MEMORY has effect on heap size of thriftserver
> -----------------------------------------------------------
>
> Key: SPARK-10839
> URL: https://issues.apache.org/jira/browse/SPARK-10839
> Project: Spark
> Issue Type: Bug
> Components: Spark Submit
> Affects Versions: 1.4.1, 1.5.0
> Reporter: Yun Zhao
>
> When SPARK_DAEMON_MEMORY in spark-env.sh is setted to modify memory of Master
> or Worker, there's an effect on heap size of thriftserver, further, this
> effect cannot be modified by spark.driver.memory or --driver-memory. Version
> 1.3.1 does not have the same problem.
> in org.apache.spark.launcher.SparkSubmitCommandBuilder:
> {quote}
> String tsMemory =
> isThriftServer(mainClass) ? System.getenv("SPARK_DAEMON_MEMORY") :
> null;
> String memory = firstNonEmpty(tsMemory,
> firstNonEmptyValue(SparkLauncher.DRIVER_MEMORY, conf, props),
> System.getenv("SPARK_DRIVER_MEMORY"), System.getenv("SPARK_MEM"),
> DEFAULT_MEM);
> cmd.add("-Xms" + memory);
> cmd.add("-Xmx" + memory);
> {quote}
> SPARK_DAEMON_MEMORY has the highest priority.
> It can be modified like this:
> {quote}
> String memory = firstNonEmpty(firstNonEmptyValue(SparkLauncher.DRIVER_MEMORY,
> conf, props),
> System.getenv("SPARK_DRIVER_MEMORY"), tsMemory,
> System.getenv("SPARK_MEM"), DEFAULT_MEM);
> {quote}
