Subject Re: To create csv file without double quotes.
Date Fri, 17 Feb 2017 04:21:31 GMT

PutFile will only write the bytes that exist for that flowfile.  It
won't manipulate content in any way.  I recommend using the provenance
feature of nifi to look at each stage of the flow and follow the
lineage of an object.  With this you should clearly see where the
quotation issue is being introduced.
