Hi Scott,
Yes, there is a minor change you have to make to enable the glusterfs stacks.
You will need to update the metainfo.xml for the 2.1.GlusterFS stack.
This can be accomplished by issuing the following from a command line:
sed -i ‘s/’false’/true/’ /var/lib/ambari-server/resources/stacks/HDP/2.1.GlusterFS/metainfo.xml
Also you can update it manually by opening /var/lib/ambari-server/resources/stacks/HDP/2.1.GlusterFS/metainfo.xml and changing the active flag from false to true.
If you have already deployed a cluster on the prospective servers, you will need to issue an
ambari-server reset -s
before you change the metainfo.xml file.
Good luck!
Erin
