---------------------------
Summary: Store invocation in local mode brings sire effect
Key: PIG-3347
URL: https://issues.apache.org/jira/browse/PIG-3347
Project: Pig
Issue Type: Bug
Components: grunt
Affects Versions: 0.11
Environment: local mode
Reporter: Sergey
The problem is that intermediate 'store' invocation "changes" the final store
output. Looks like it brings some kind of side effect. We did use 'local' mode
to run script
here is the input data:
1
1
Here is the script:
{code}
a = load 'test';
a_group = group a by $0;
b = foreach a_group {
a_distinct = distinct a.$0;
generate group, a_distinct;
}
--store b into 'b';
c = filter b by SIZE(a_distinct) == 1;
store c into 'out';
{code}
We expect output to be:
1 1
The output is empty file.
Uncomment {code}--store b into 'b';{code} line and see the diffrence.
Yuo would get expected output.
