JDK Installation Install the JDK under Oracle, I installed JDK 1.7, install the new system environment variable java_home, the variable value is "C:\ProgramFiles\Java\jdk1.7.0_79", depending on the installation of the road. Add C:\Program Files\java\jdk1.7.0_79\bin and C:\ProgramFiles\Java\jre7\bin at the same time under the system variable path. 1.2

Spark standalone cluster is a cluster mode in the master-slaves architecture. Like most master-slaves cluster clusters, there is a single point of failure (spof) in the master node. Spark provides two solutions to solve this single point of failure problem: Single-node recovery with local file system) Zookeeper-based standby Masters (standby masters with zookeeper) Zookeeper provides a leader election m

The installation of Spark is divided into several modes, one of which is the local run mode, which needs to be decompressed on a single node without relying on the Hadoop environment. Run Spark-shell Local mode running Spark-shell is very simple, just run the following command, assuming the current directory is $spark_home $ master=local $ bin/
