6. Download Companion Files

We have provided a set of companion files, including script files (scripts.zip) and configuration files (configuration_files.zip), that you should download and use throughout this process. Download and extract the files:

wget http://public-repo-1.hortonworks.com/HDP/tools/2.1.2.1/hdp_manual_install_rpm_helper_files-2.1.2.471.tar.gz

Hortonworks strongly recommends that copy the contents to your ~/.bash_profile) to set up these environment variables in your environment.

The following provides a snapshot of a sample script file to create Hadoop directories. This sample script file sources the files included in Companion Files.

#!/bin/bash 
./users.sh 
./directories.sh

echo "Create datanode local dir"
mkdir -p $DFS_DATA_DIR;
chown -R $HDFS_USER:$HADOOP_GROUP $DFS_DATA_DIR;
chmod -R 750 $DFS_DATA_DIR;

echo "Create yarn local dir"
mkdir -p $YARN_LOCAL_DIR;
chown -R $YARN_USER:$HADOOP_GROUP $YARN_LOCAL_DIR;
