Subject [jira] [Commented] (FALCON-265) reverse lookup for falcon entity definition
Date Thu, 06 Mar 2014 07:01:48 GMT

    [ https://issues.apache.org/jira/browse/FALCON-265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13922079#comment-13922079

Shwetha G S commented on FALCON-265:
------------------------------------

For 1, I wasn't planning on extending entity graph. getDependencies returns list of entities.
I was planning to just iterate over it and check if its input/output. When we move getDependencies()
to use new graph used by lineage, even this can change
For 2, FALCON-301 adds a map of path to feed name. I will just piggy back on it

> Can we have an option to reverse lookup an entityspecification?
> For instance, 
> 1. Given a path find the corresponding feed definition.
> 2. Given an input feed name, list the corresponding processes.
> Note that [2] is not the same as -dependency option, since depedency option list all
dependencies, including both input and output.
