> when run distcp with -log /logpath -v, distcp will print copy status and file
> info to /logpath, but print log with wrong file zise. The logs print as
> follows:
> FILE_COPIED: source=hdfs://ns1/test/stax2-api-3.1.4.jar, size=161867 -->
> target=hdfs://ns1/tmp/target/stax2-api-3.1.4.jar, size=0
> As I analysis ,the root cause is as follows:
> targrtFileStatus got before copying. So targrtFileStatus is null. Here should
> get targrtFileStatus again after file copying.
