Summary: Pig 12.0 Documentation
Key: PIG-3777
URL: https://issues.apache.org/jira/browse/PIG-3777
Project: Pig
Issue Type: Wish
Components: documentation
Affects Versions: 0.12.0
Reporter: Karina Hauser
Priority: Trivial
I think the example for SAMPLE is wrong
In this example, a scalar expression is used (it will sample approximately 1000
records from the input).
a = load 'a.txt';
b = group a all;
c = foreach b generate COUNT(a) as num_rows;
e = sample d 1000/num_rows;
There is no relation d and I get a "Projected field [num_rows] does not exist
in schema" error, I think it need to be
e = sample a 1000/c.numrows
