Description

With the latest build on master, I submitted the following cluster:

<cluster colo="local" description="Local cluster" name="local" xmlns="uri:falcon:cluster:0.1">
    <interfaces>
        <interface type="readonly" endpoint="hftp://localhost:50010" version="1.1.2"/>

        <interface type="write" endpoint="hdfs://localhost:8020" version="1.1.2"/>

        <interface type="execute" endpoint="localhost:8021" version="1.1.2"/>

        <interface type="workflow" endpoint="http://localhost:11000/oozie/" version="4.0.0"/>

        <interface type="messaging" endpoint="tcp://localhost:61616"  version="5.7.0"/>
    </interfaces>
    <locations>
        <location name="staging" path="/falcon/staging"/>
        <location name="temp" path="/falcon/tmp"/>
        <location name="working" path="/falcon/working"/>
    </locations>
    <properties>
    </properties>
</cluster>

with:

bin/falcon entity -submit -type cluster -file local.xml

The submit is OK, and I can see the cluster in the Falcon configuration store:

bin/falcon entity -list -type cluster
(cluster) local(null)

Now, I create the following feed:

<feed description="" name="output" xmlns="uri:falcon:feed:0.1">
    <groups>output</groups>

    <frequency>minutes(10)</frequency>

    <clusters>
        <cluster name="local">
            <validity start="2012-07-20T03:00Z" end="2099-07-16T00:00Z"/>
            <retention limit="hours(10)" action="delete"/>
        </cluster>
    </clusters>

    <locations>
        <location type="data" path="/data/output"/>
    </locations>
  
    <ACL owner="jbonofre" group="supergroup" permission="0x644"/>

    <schema location="none" provider="none"/>

</feed>

However, when I try to submit this feed, I got:

bin/falcon entity -submit -type feed -file ~/demo/entity/output.xml 
Error: Cluster entity vertex must exist: local

whereas local cluster exists.

It seems that it's a regression introduced in EntityRelationshipGraphBuilder.

I gonna take a look on that.
