Subject [jira] [Created] (GIRAPH-162) BspCase.setup() should catch FileNotFoundException thrown from org.apache.hadoop.fs.FileSystem.listStatus()

BspCase.setup() should catch FileNotFoundException thrown from org.apache.hadoop.fs.FileSystem.listStatus()
-----------------------------------------------------------------------------------------------------------

                 Key: GIRAPH-162
                 URL: https://issues.apache.org/jira/browse/GIRAPH-162
             Project: Giraph
          Issue Type: Bug
          Components: test
            Reporter: Eugene Koontz


In hadoop trunk, org.apache.hadoop.fs.FileSystem.listStatus() is declared to throws both FileNotFoundException
and IOException. The former (FileNotFoundException) is currently not caught when BspCase.setup()
looks for the GiraphJob.ZOOKEEPER_MANAGER_DIR_DEFAULT directory in order to delete it. The
listStatus() call throws FileNotException if this directory does not exist and causes several
tests to fail when using Hadoop trunk. This exception should be caught and ignored during
setup(), since it's not an error for this directory not to exist.
