[jira] [Created] (SQOOP-2339) Move sub-directory might fail in append mode

Qian Xu created SQOOP-2339:
------------------------------

             Summary: Move sub-directory might fail in append mode
                 Key: SQOOP-2339
                 URL: https://issues.apache.org/jira/browse/SQOOP-2339
             Project: Sqoop
          Issue Type: Bug
    Affects Versions: 1.4.5
            Reporter: Qian Xu
            Assignee: Qian Xu
             Fix For: 1.4.7


In append mode, Sqoop will first create dataset in a temporary directory and then move it target directory. I noticed that if the temporary directory contains  sub-directory and the target directory has a same directory, the import might fail with an IOException. This will happen in old hadoop distribution such as hadoop-2.0.4-alpha. 

There is no problem with hadoop-2.5.0. With hadoop-2.5.0, duplicated directory will be renamed by adding a suffix "-0000" (the digit might be increased).
