Masatake Iwasaki commented on HDFS-8844:
----------------------------------------
Failed tests are copying non-existent file to {{CLITEST_DATA/file}} but
expected output could not be given if the tartget {{CLITEST_DATA/file}} exists.
The cause is test for {{getmerge}} creating {{CLITEST_DATA/file}} but not
deleting it.
