[jira] [Created] (NIFI-6853) flowFileEvent combineCounters hashmap overwritten

Iván Ezequiel Rodriguez created NIFI-6853:
---------------------------------------------

             Summary: flowFileEvent combineCounters hashmap overwritten
                 Key: NIFI-6853
                 URL: https://issues.apache.org/jira/browse/NIFI-6853
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.10.0
            Reporter: Iván Ezequiel Rodriguez
            Assignee: Iván Ezequiel Rodriguez


This error is similar to that of Nifi 6800:

[https://issues.apache.org/jira/browse/NIFI-6800|https://issues.apache.org/jira/browse/NIFI-6800]

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
