Pragya Mittal commented on FALCON-1526:
---------------------------------------
According to recent observations , this bug is not specific to lifecycle. Any
feed/process containing multiple clusters (lifecycle may or may not be defined)
when updated will lead to bundle duplication on all the clusters defined in
that feed/process.
Example feed definition :
{noformat}
<?xml version="1.0" encoding="UTF-8"?><feed xmlns="uri:falcon:feed:0.1"
name="PrismFeedUpdateTest-agregated-logs16-bba5ed74" description="clicks log">

<late-arrival cut-off="hours(6)"/>
<clusters>
<cluster name="PrismFeedUpdateTest-corp-c228e1ca" type="source">
<validity start="2015-10-13T13:24Z" end="2099-01-01T00:00Z"/>

</cluster>
<cluster name="PrismFeedUpdateTest-corp-6d3bec13" type="target">
