Output location strict check
Pig scripts could contain multiple STORE statements. There are cases when one would like to avoid writing to the same output location. Pig provides admins/script writers with a property to check if multiple STORE statements make an attempt to write to the same output directory. And fail fast letting the user know of the same.
Specifically this makes sense for file-based output locations (HDFS, Local FS, S3..) to avoid Pig script from failing when multiple MR jobs write to the same location.
To enforce strict checking of output location, set pig.location.check.strict=true. See also Pig Properties on how to set this property.
