Olivier Girardot closed SPARK-7327.
-----------------------------------
Resolution: Cannot Reproduce
I can't seem to reproduce the issue and I did not attach any repro step...
Sorry I'm closing this as "Cannot reproduce" until I find back my failing
example.
Thanks for your time.
> DataFrame show() method doesn't like empty dataframes

> If no-one takes it by next friday, I'll fix it, the problem seems to come
> from the colWidths method :
> {code}
> // Compute the width of each column
> val colWidths = Array.fill(numCols)(0)
> for (row <- rows) {
> for ((cell, i) <- row.zipWithIndex) {
> colWidths(i) = math.max(colWidths(i), cell.length)
> }
> }
> {code}
