> In FileUtils.java the following code does not get executed even when src
> directory size is greater than HIVE_EXEC_COPYFILE_MAXSIZE because
> srcFS.getFileStatus(src).getLen() returns 0 when src is a directory. We
> should use srcFS.getContentSummary(src).getLength() instead.

> srcFS.getFileStatus(src).getLen() >
