> A'A and possibly A'B can fail with an index out of bounds on the row vector.
> This seems related to partitioning where some partitions may be empty.
> This can be reproduce with the attached data as input into
> spark-itemsimilarity. This is only A data and the one large csv will complete
> correctly but passing in the directory of part files will exhibit the error.
> The data is identical except in the number of files that are used to contain
> the data.
> The error occurs using the local raw filesystem and with master = local and
> is pretty fast to reach.
