3.2. hbase-env.sh

Set HBase environment variables in this file. Examples include options to pass the JVM on start of an HBase daemon such as heap size and garbarge collector configs. You also set configurations for HBase configuration, log directories, niceness, ssh options, where to locate process pid files, etc., via settings in this file. Open the file at conf/hbase-env.sh and peruse its content. Each option is fairly well documented. Add your own environment variables here if you want them read by HBase daemon startup.

Changes here will require a cluster restart for HBase to notice the change.
