> I'm hitting this from data coming from Spark while retrieving this data frame:
>
>
> {code:java}
> <database> <name> <temp>
> default a TRUE
> b TRUE
> {code}
>
> Error:
> {code:java}
> error: Failed to fetch data: invalid data in buffer 2
> {code}
> The problem is that is possible to have a NULL character array with offsets
> set to 0, notice that in the example above Spark returns two batches, so
> effectively, we are trying to parse:
>
> {code:java}
> <database> <name> <temp>
> b TRUE
> {code}
>
> Where the data array is NULL and the offsets 0s for the <database> columns.
