Is there a collaborative document for service "Custom commands"?

Some of the custom commands I know are :

DECOMMISSION/RECOMMISSION and

CLEAN for hive.

Is there an API to get all the custom commands? Or a doc with details of custom commands that can be run for services?

The custom commands are actually defined at the service-level in the metainfo.xml file. E.g.,

HDFS: DECOMMISSION, REBALANCEHDFS Hbase: DECOMMISSION YARN: REFRESHQUEUES, CREATE_YARN_DIRECTORIES (needed for LLAP in a Kerberized cluster) Knox: STARTDEMOLDAP, STOPDEMOLDAP Hive: CLEAN, RESTART_LLAP Kerberos: SET_KEYTAB, REMOVE_KEYTAB

I've not seen a comprehensive document that details which commands are available for which services, but the Ambari CWiki page has some great usage scenarios and FAQs that may help.
