             Summary: FileBasedOutputSizeReader does not calculate size of files in sub-directories
                 Key: PIG-3891
                 URL: https://issues.apache.org/jira/browse/PIG-3891
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.12.0
            Reporter: Rohini Palaniswamy


FileBasedOutputSizeReader only includes files in the top level output directory. So if files are stored under subdirectories (For eg: MultiStorage), it does not have the bytes written correctly. 

0.11 shows the correct number of total bytes written and this is a regression. A quick look at the code shows that the JobStats.addOneOutputStats() in 0.11 also does not recursively iterate and code is same as  FileBasedOutputSizeReader. Need to investigate where the correct value comes from in 0.11 and fix it in 0.12.1/0.13.
