Subject Wrong and non consistent behavior of max
Date Thu, 27 Nov 2014 15:14:05 GMT
Hi Flinksters,

I don't if I made something wrong, but the code seems fine. Basically the
max function does extract a wrong element.

The error does just happen with my real data, not if I inject some sequence
into costs.

The problem is that the according tuple value at position is wrong. The
maximum of the second part is detected correctly.

The code snippet:

val maxCost = costs map {x => (x.id, x.value)} max(1)

(costs map {x => (x.id, x.value)} map {_ toString} map {"first: "+ _ })
union (maxCost map {_ toString} map {"second: "+ _ }) writeAsText
config.outFile

The output:
