Description Mike Fiedler 2018-05-07 18:53:14 UTC 
Description of problem:

This looks the same as:  https://bugzilla.redhat.com/show_bug.cgi?id=1548104

It looks like the elasticsearch_genid work is not present in running pods.  See below for the configmap and directory listing for the fluentd pod

Version-Release number of selected component (if applicable): 3.10.0-0.32.0


How reproducible: Always in the 3.10 scale lab.  700 pods logging 1 message/second each results in many duplicates

@jcantril is aware and is working to synch the OCP images

Actual results:

Duplicate index entries when bulk index full retries occur

Expected results:

Successful retries of bulk index full errors with no duplicates
