Skewed join doesn't handle empty input directory
------------------------------------------------
Key: PIG-1513
URL: https://issues.apache.org/jira/browse/PIG-1513
Project: Pig
Issue Type: Bug
Reporter: Richard Ding
Assignee: Richard Ding
Fix For: 0.8.0
The following script
{code}
A = load 'input';
B = load 'emptydir';
C = join B by $0, A by $0 using 'skewed';
dump C
{code}
fails with "ERROR: java.lang.RuntimeException: Empty samples file';
In this case, the sample job has 0 maps. Pig doesn't expect this and fails .
