---------------------------------
Summary: PluckTuple overwrites regex if used more than once in the
same script
Key: PIG-4808
URL: https://issues.apache.org/jira/browse/PIG-4808
Project: Pig
Issue Type: Bug
Affects Versions: 0.15.0
Reporter: Eyal Allweil
Assignee: Eyal Allweil
If you define two PluckTuples with different regexes, and use them together,
they will overwrite the regex field of one another's (this will not affect
cases where non-regex prefixes are used).
Example (from testOutput in TestPluckTuple.java, modified)
a = load 'a' using mock.Storage();
b = load 'b' using mock.Storage();
c = join a by x, b by x;
define pluck1 PluckTuple('a::.*');
define pluck2 PluckTuple('b::.*');
d = foreach c generate pluck1(*) AS pluck1, pluck2(*) AS pluck2;
Expected:
((1,hey,2),(1,sasf,5))
((2,woah,3),(2,woah,6))
Actual:
((1,sasf,5),(1,sasf,5))
((2,woah,6),(2,woah,6))
