NIFI-2262: Added Avro-normalization of table/column names in SQL processors
This closes #994.
> SQL processors fail if column name contains characters illegal for Avro
> -----------------------------------------------------------------------
>
> Key: NIFI-2262
> URL: https://issues.apache.org/jira/browse/NIFI-2262
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Fix For: 1.1.0
>
>
> For SQL processors that output Avro (ExecuteSQL, QueryDatabaseTable, etc.),
> if the SQL result set contains columns whose names contain Avro-illegal
> characters (such as a period), then an error occurs:
> org.apache.avro.SchemaParseException: Illegal character in: user.gender
> These processors should either normalize the names for Avro automatically or
> have a property indicating whether names should be normalized.
> A workaround for ExecuteSQL in many cases is to alias the columns in the SQL.
> This approach doesn't currently work in QueryDatabaseTable for incremental
> fetch (i.e. maximum-value columns)
