[10:19:57] davideagnello: there are a couple of changes that are required in order to address the issues related to this bug
[10:21:41] davideagnello: the first being where we persist all job related data
[10:21:54] davideagnello: the second, when we delete old job related data
[10:22:40] davideagnello: the issue is that zookeeper runs out of heap space because data we save to it is never deleted and overtime it runs out of heap space

    never gets deleted.this patch allows us to enable a flag in cue-config
