I have these "rows"
({(155495400)})
({(199027860),(199027860),(149167529),(203508790),(198488630)})
({(174255619),(201077556),(199051606),(198778302)})
I believe the correct way to explain them would be each row/tuple is a
bag that contains tuples of size 1? Is that right?
Anyway, is there something native or UDF I can use to convert them to
this format?
(155495400)
(199027860 199027860 149167529 203508790 198488630)
(174255619 201077556 199051606 198778302)
Maybe if I explain what we are trying to do it would help.
We have logs of users to product views in a tab delimited format.
foo\t1234
bar\t1234
foo\t4423
baz\t5563
We simply want product views grouped by user and outputed on 1 line.
1234 4423
1234
5563
The above first line would be from the user foo, second bar and third baz.
Thanks
