spark--spark9.0安装【1】

spark：

Spark是下一代In Memory MR计算框架，性能上有数量级提升，同时支持Interactive Query、流计算、图计算等。支持java、scala

适用范围：

1.高性能机器学习2.即时计算

下载：

http://spark.apache.org/downloads.html

安装：

spark纯粹模式：

这种模式就是一个单一的spark集群或者单spark测试机抑或开发机。
1.在集群各个节点安装编译好的spark版本，也可以自己编译安装，自己编译点击此处。在conf/slaves中需要将需要使用的worker的hostname包含进去，和hadoop的slaves文件配置类型。
2.启动spark

./sbin/start-master.sh

3.启动后master会首先输出

spark://HOST:PORT

的url，也可以在mater的 http://localhost:8080上找到这个url的。
4.使用如下的命令启动worker并连接到master

./bin/spark-class org.apache.spark.deploy.worker.Worker spark://IP:PORT

5.在master上用http://localhost:8080这个地址对集群进行监控
6.又和hadoop类似，spark集群需要无密码访问的ssh
7.使用在

SPARK_HOME/bin的如下脚本对spark集群进行管理：

sbin/start-master.sh

- 启动master实例.

sbin/start-slaves.sh

- 启动在

conf/slaves文件里的worker实例

.

sbin/start-all.sh

-启动整个集群.

sbin/stop-master.sh

- 停止通过

bin/start-master.sh

脚本启动的实例.

sbin/stop-slaves.sh

- 停止通过

bin/start-slaves.sh脚本启动的实例

.

sbin/stop-all.sh

- 停止整个集群.8.使用conf/spark-env.sh.template创建配置环境变量的conf/spark-env.sh文件。

Environment Variable	Meaning
SPARK_MASTER_IP	Bind the master to a specific IP address, for example a public one.
SPARK_MASTER_PORT	Start the master on a different port (default: 7077).
SPARK_MASTER_WEBUI_PORT	Port for the master web UI (default: 8080).
SPARK_WORKER_PORT	Start the Spark worker on a specific port (default: random).
SPARK_WORKER_DIR	Directory to run applications in, which will include both logs and scratch space (default: SPARK_HOME/work).
SPARK_WORKER_CORES	Total number of cores to allow Spark applications to use on the machine (default: all available cores).
SPARK_WORKER_MEMORY	Total amount of memory to allow Spark applications to use on the machine, e.g. 1000m , 2g (default: total memory minus 1 GB); note that each application's individual memory is configured using its spark.executor.memory property.
SPARK_WORKER_WEBUI_PORT	Port for the worker web UI (default: 8081).
SPARK_WORKER_INSTANCES	Number of worker instances to run on each machine (default: 1). You can make this more than 1 if you have have very large machines and would like multiple Spark worker processes. If you do set this, make sure to also set SPARK_WORKER_CORES explicitly to limit the cores per worker, or else each worker will try to use all the cores.
SPARK_DAEMON_MEMORY	Memory to allocate to the Spark master and worker daemons themselves (default: 512m).
SPARK_DAEMON_J***A_OPTS	JVM options for the Spark master and worker daemons themselves (default: none).
