[jira] [Created] (CRUNCH-683) Avoid unnecessary listStatus calls from getSize computation

Jon Hemphill created CRUNCH-683:
-----------------------------------

             Summary: Avoid unnecessary listStatus calls from getSize computation
                 Key: CRUNCH-683
                 URL: https://issues.apache.org/jira/browse/CRUNCH-683
             Project: Crunch
          Issue Type: Improvement
          Components: Core
    Affects Versions: 0.14.0
            Reporter: Jon Hemphill
            Assignee: Josh Wills


The getPathSize computation in SourceTargetHelper currently makes unnecessary listStatus calls when recursing over a directory, which can cause performance issues when the filesystem is an object store such as S3. The performance can be improved with the addition of a private method to use for the getPathSize recursion that takes a known FIleStatus object as a parameter.
