Subject [jira] [Commented] (AMBARI-2071) Cluster install wizard does not work with client-only service
Date Thu, 02 May 2013 14:56:16 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-2071?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13647592#comment-13647592
] 

Trevor McKay commented on AMBARI-2071:
--------------------------------------

This seems to be because the response to the PUT has 0 content, and the UI is expecting a
response.  From Firebug:

Request is http://localhost:8080/api/v1/clusters/test14/services?ServiceInfo/state=INSTALLED
Source is {"ServiceInfo": {"state": "STARTED"}}

Response Headers
Content-Length	0
Content-Type	text/plain
Server	Jetty(7.6.7.v20120910)

Response status is 200 OK


** Note, if a service check is added for this service, the install will complete.  The service
check causes a non-zero IN_PROGRESS response because stage creation does not return a null
value.  However, this workaround seems to only be successful on a single host when the cluster
involves multiple hosts because the service check is only run on a single host (theory).

> If the cluster install wizard is used to install a single client only service, the wizard
will hang after trying to move the service from INSTALLED -> STARTED.
