> CSVReader Can't Derive Schema from Quoted Headers
> -------------------------------------------------
>
> Key: NIFI-5552
> URL: https://issues.apache.org/jira/browse/NIFI-5552
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.7.1
> Reporter: Shawn Weeks
> Assignee: Pierre Villard
> Priority: Minor
> Time Spent: 20m
> Remaining Estimate: 0h
>
> When deriving the schema from a CSV File Header NiFi is unable to generate a
> valid schema if the Header Columns are Double Quoted even though the
> CSVReader is set to handle quotes. Using the nile.csv sample file from
> https://people.sc.fsu.edu/~jburkardt/data/csv/csv.html results in an Illegal
> initial character exception in the Avro Schema generator. In this specific
> case the header did not contain any spaces or special characters though it
> was case sensitive.
> {code:java}
