spark set hadoop configuration

hadoop uses an ip address for scheduled access, even if it accesses its own machine, if no password is configured for access, you need to enter a password for access. This is the same as when configuring the hadoop standalone mode. You need to configure password-free access. [Hduser @ gdy192 ~] $ Ssh-copy-id-I. ssh/id_rsa.pub hduser @ gdy192 Verify that gdy192 has accessed gdy194 without a password. [Hdus

. The main configuration file is actually hadoop-env.sh and core-site.xml, hdfs-site.xml and mapred-site.xml. First look at the hadoop-env.sh: First, configure java_home. Needless to say, download the latest GZ package from Oracle and decompress it directly. Set the path. Then I think these configurations are very us

Storage System spark tasks need to load data from some external storage system (e.g. HDFS or HBase), it is important that the storage system is close to the spark system, we have the following recommendations: (1) If possible, run spark on the same HDFS node, The simplest approach is to create a cluster-independent pattern that raises the same node (http://spark.

Install Hadoop in standalone mode-(1) install and set up a virtual environment for hadoop StandaloneZookeeper There are a lot of articles on how to install Hadoop in standalone mode on the network. Most of the articles that follow these steps fail, and many detours have been taken, but all the problems have been solved

logData = sc.textFile(logFile, 2).cache() val numAs = logData.filter(line => line.contains("a")).count() val numBs = logData.filter(line => line.contains("b")).count() println("Lines with a: %s, Lines with b: %s".format(numAs, numBs)) } } The program calculates the number of rows in the/usr/local/spark/readme file that contain "a" and the number of rows that contain "B".The program relies on the

Elastic distribution Data Set RddThe RDD (resilient distributed Dataset) is the most basic abstraction of spark and is an abstraction of distributed memory, implementing an abstract implementation of distributed datasets in a way that operates local collections. The RDD is the core of Spark, which represents a collection of data that has been partitioned, immutab

You can also deploy namenode, datanode, jobtracker, and tasktracker on one machine.
