Ken Goodhope commented on PIG-1890:
-----------------------------------
A recent change in Pig causes setLocation to be called twice, and if
setLocation isn't idempotent, then you get twice the output. My suspicion is
UNION is further exasperating the problem leading to the input being added 4X.
Did you still see the problem with the last patch I added?
> Fix piggybank unit test TestAvroStorage

> Key: PIG-1890
> URL: https://issues.apache.org/jira/browse/PIG-1890
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: 0.9.0
> Reporter: Daniel Dai

> TestAvroStorage fail on trunk. There are two reasons:
> 1. After PIG-1680, we call LoadFunc.setLocation one more time.
> 2. The schema for AvroStorage seems to be wrong. For example, in first test
> case testArrayDefault, the schema for "in" is set to "PIG_WRAPPER: (FIELD:
> {PIG_WRAPPER: (ARRAY_ELEM: float)})". It seems PIG_WRAPPER is redundant. This
> issue is hidden until PIG-1188 checked in.
