> It has been observed that TestDFSAdmin frequently fails tests, such as 
> [PR-6620|https://github.com/apache/hadoop/pull/6620]. The failure occurs when 
> the test method testDecommissionDataNodesReconfig asserts the first line of 
> the standard output. The issue arises when the content being checked does not 
> appear on a single line. I believe we should change the method of testing. 
> The standard output content, which was printed in 
> [PR-6620|https://github.com/apache/hadoop/pull/6620], is as follows :
