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

[#1]

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?

@sbhat

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.

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
