    NIFI-4286: Fix NPE in GenerateTableFetch when Partition Size = 0


> GenerateTableFetch with Partition Size of 0 produces NPE
> --------------------------------------------------------
>                 Key: NIFI-4286
>                 URL: https://issues.apache.org/jira/browse/NIFI-4286
>             Project: Apache NiFi
>          Issue Type: Bug
>    Affects Versions: 1.3.0
>            Reporter: Bryan Bende
>            Assignee: Matt Burgess
>            Priority: Minor
> The description of partition size says "A value of zero indicates that a 
> single FlowFile is to be generated whose SQL statement will fetch all rows in 
> table".
> If you set the partition size to 0 the processor will get an NPE at these two 
> lines:
> long limit = partitionSize == 0 ? null : partitionSize;
> long offset = partitionSize == 0 ? null : i * partitionSize;
