> Assignee: Iván Ezequiel Rodriguez
> Priority: Major
> Labels: core, counters, framework, nifi, overwrite,
> overwriteExisting
> Fix For: 1.11.0

> Time Spent: 50m
> Remaining Estimate: 0h
>
> It is related to the bug I reported a few days ago +*NIFI-6800*+
> This is another problem in the StandardProcessSession.java, promptly in the
> combination of the counters for the event repository-> flowFileEvent object.
> The putALL method is called and the values are not being mixed when it
> comes to existing keys
> As we know hashmap does not allow duplicate keys. So when we merge the maps
> in this way, for duplicate keys in map1 the value is overwitten by value for
> same key in map2.
> *_The putAll method cannot be used to combine hashmasp if what is expected is
> that the keys be summed_*.
