Koji Noguchi updated PIG-2968:
------------------------------
Attachment: pig-2968-trunk_v03.txt
bq. Actually, can you please fix the indentation of testPruneSubTreeForEach()
using 4 spaces?
Changed. (Sorry, I recently learned it's 4 spaces instead of 2.)
bq. Or at least some Assert?
Added a catch and fail call.
bq. Should we take a crack at this before committing this
I tried simply taking out the lines but nested foreach with pruned inputs were
different from a simple foreach with just one output. (one extra foreach on
former)
> ColumnMapKeyPrune fails to prune a subtree inside foreach

> daily = load 'nyse' as (exchange, symbol);
> grpd = group daily by exchange;
