RE: Specifying multiple input paths

[Olga Natkovich]

Tom,

You are correct that currently we only allow a single glob in the load
statement. It would not be hard to extend it to multiple globs. I have
created a JIRA for it: https://issues.apache.org/jira/browse/PIG-252;
maybe somebody will be interested to contribute a patch.
