Cheolsoo Park updated PIG-3643:
-------------------------------
Attachment: PIG-3643-1.patch
Uploading a patch that fixes the regression.
To summarize the issue-
# Before PIG-3581:
{code}
if X, do a
else if Y, do b
else do c
{code}
# With PIG-3581:
{code}
If Y && N, do b
else if X, do a
else do c
{code}
As can be seen, if Y && !N, it falls into c now while we used to fall into b.
# With my patch:
{code}
If Y && N, do b
else if X, do a
else if Y, do b
else do c
{code}
I verified-
* TestColumnAliasConversion passes.
* TestLogicalPlanGenerator passes.
* The new test cases added by PIG-3581 pass.
* The example in this jira wrks.
> Nested Foreach with UDF and bincond is broken

> Was checking out PIG-3000.
> A = load 'data' as (a:chararray);
> B = foreach A { c = UPPER(a); generate ((c eq 'TEST') ? 1 : 0), ((c eq 'DEV')
> ? 1 : 0); }
> This now throws "Invalid field projection. Projected field [c] does not exist
> in schema". Works fine in 0.11. Broken in trunk. Haven't checked 0.12.
