| # This file is sourced when running various Spark programs. |
| # Copy it as spark-env.sh and edit that to configure Spark for your site. |
| |
| # Options read when launching programs locally with |
| # ./bin/run-example or ./bin/spark-submit |
| # - HADOOP_CONF_DIR, to point Spark towards Hadoop configuration files |
| # - SPARK_LOCAL_IP, to set the IP address Spark binds to on this node |
| # - SPARK_PUBLIC_DNS, to set the public dns name of the driver program |
| |
| # Options read by executors and drivers running inside the cluster |
| # - SPARK_LOCAL_IP, to set the IP address Spark binds to on this node |
| # - SPARK_PUBLIC_DNS, to set the public DNS name of the driver program |
| # - SPARK_LOCAL_DIRS, storage directories to use on this node for shuffle and RDD data |
| # - MESOS_NATIVE_JAVA_LIBRARY, to point to your libmesos.so if you use Mesos |
| |
| # Options read in YARN client/cluster mode |
| # - SPARK_CONF_DIR, Alternate conf dir. (Default: ${SPARK_HOME}/conf) |
| # - HADOOP_CONF_DIR, to point Spark towards Hadoop configuration files |

| # - SPARK_EXECUTOR_MEMORY, Memory per Executor (e.g. 1000M, 2G) (Default: 1G) |
| # - SPARK_DRIVER_MEMORY, Memory for Driver (e.g. 1000M, 2G) (Default: 1G) |
| |
| # Options for the daemons used in the standalone deploy mode |
| # - SPARK_MASTER_HOST, to bind the master to a different IP address or hostname |
| # - SPARK_MASTER_PORT / SPARK_MASTER_WEBUI_PORT, to use non-default ports for the master |
| # - SPARK_MASTER_OPTS, to set config properties only for the master (e.g. "-Dx=y") |
| # - SPARK_WORKER_CORES, to set the number of cores to use on this machine |
| # - SPARK_WORKER_MEMORY, to set how much total memory workers have to give executors (e.g. 1000m, 2g) |
| # - SPARK_WORKER_PORT / SPARK_WORKER_WEBUI_PORT, to use non-default ports for the worker |
| # - SPARK_WORKER_DIR, to set the working directory of worker processes |
| # - SPARK_WORKER_OPTS, to set config properties only for the worker (e.g. "-Dx=y") |
| # - SPARK_DAEMON_MEMORY, to allocate to the master, worker and history server themselves (default: 1g). |
| # - SPARK_HISTORY_OPTS, to set config properties only for the history server (e.g. "-Dx=y") |
| # - SPARK_SHUFFLE_OPTS, to set config properties only for the external shuffle service (e.g. "-Dx=y") |

| # - SPARK_PID_DIR Where the pid file is stored. (Default: /tmp) |
| # - SPARK_IDENT_STRING A string representing this instance of spark. (Default: $USER) |
| # - SPARK_NICENESS The scheduling priority for daemons. (Default: 0) |
| # - SPARK_NO_DAEMONIZE Run the proposed command in the foreground. It will not output a PID file. |
| # Options for native BLAS, like Intel MKL, OpenBLAS, and so on. |
| # You might get better performance to enable these options if using native BLAS (see SPARK-21305). |
| # - MKL_NUM_THREADS=1 Disable multi-threading of Intel MKL |
| # - OPENBLAS_NUM_THREADS=1 Disable multi-threading of OpenBLAS |
