Solution

  1. Run the following command if an error message is displayed stating "JAVA_HOME is null":

    export JAVA_HOME=Java path

    Set JAVA_HOME and execute the installation script again.

  2. If a Flume client has been installed under the specified directory, uninstall the client and use another directory.
