| ### Script requires package bigtop-groovy to be installed |
| # Use this script to initialize HDFS directory structure for various components |
| # to run. This script can be run from any node in the Hadoop cluster but should |
| # only be run once by one node only. |
| # installed. Unless you are using psuedo distributed cluster, this node is most |
| # likely NOT your namenode |
| # Steps to be performed before running this script: |
| # 1. Stop the namenode and datanode services if running. |
| # 2. Format namenode (su -s /bin/bash hdfs hdfs namenode -format). |
| # 3. Start the namenode and datanode services on appropriate nodes. |
| |
| # Autodetect JAVA_HOME if not defined |
| if [ -f /usr/lib/bigtop-utils/bigtop-detect-javahome ]; then |
| . /usr/lib/bigtop-utils/bigtop-detect-javahome |
