max.width.per.endpoint - how many minor fragments you can have per major
fragment on a single node

global.max.width - max number of minor fragments per major fragment you can
have across all nodes

affinity.factor - When deciding how many minor fragments to schedule on
each node,
this is the factor by which you favor nodes which have data locality vs.
nodes which do not.

executor.threads -  Seems like maximum number of threads we can have ? I am
not very sure about this one.

These messages are debug messages, not errors.

So, what is the problem you have ?

Thanks
Padma
