Create an extension directory
Code Block $ mkdir -p /opt/cdap/master/ext/hbase/repl
Copy your jar to the directory
Code Block $ cp myextension.jar /opt/cdap/master/ext/hbase/repl/
Modify cdap-site.xml to use your implementation of HBaseDDLExecutor
Code Block <property> <name>hbase.ddlexecutor.extension.dir</name> <value>/opt/cdap/master/ext/hbase</value> </property>
Modify cdap-site.xml with any properties required by your executor. Anything prefixed by 'cdap.hbase.spi.hbase.' will be available through the Context object passed into your executor's initialize method
