Subject [jira] [Commented] (FALCON-662) Fetch relationships for a given type API
Date Tue, 09 Sep 2014 04:57:28 GMT

    [ https://issues.apache.org/jira/browse/FALCON-662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14126599#comment-14126599
] 

Balu Vellanki commented on FALCON-662:
--------------------------------------

After discussing with [~svenkat], we decided that optional params cluster, start and end are
not needed for this API. 
Renamed "graphs/lineage" to "metadata".

Patch attached.

> Fetch all the entities that are tagged secure for a given cluster:

> NOTE: I think its safe to assume we only list entities and then drill down to instances.
> Also the depth is 1
> These fetch the relationships for the given entity.
