Koji Noguchi updated PIG-2975:

Attachment: pig-2975-trunk_v02-broken.txt
(This patch is broken. Not intended for commit)
bq. Another option, of course, is changing the raw Comparator. We could instead

$ cat test/order.txt

222222222222...222 (repeat more than 256 time)

$ cat test/order.pig
a = load 'test/order.txt' as (a1:bytearray);
b = order a by a1;
dump b;
$ pig -x local test/order.pig

((222222222222...222))

I want getValueAsPigType to return Tuple for sorting comparisons but actual
value within Tuple for others... Still thinking.
