Daniel Urban updated KAFKA-14652:
---------------------------------
    Description: 
MirrorMaker2 runs multiple Connect worker instances in a single process. In 
Connect, the logging is based on the assumption that Connector names are 
unique. But in MM2, the same Connector names are being used in each flow 
(Connect group). This means that there is no way to differentiate between the 
logs of MirrorSourceConnector in A->B and in B->A.

This can be improved by adding the flow to the logging context and the names of 
the Connect framework threads.
