------------------------------------
The tests under streaming appear to have failed due to a missing mockito

This seems related to the MiniDFSCluster rather than this change. I've double
confirmed there is indeed no usage of this method, proceeding with commit.

> Method {{UtilTest#isCygwin}} in
> /hadoop-tools/hadoop-streaming/src/test/java/org/apache/hadoop/streaming/UtilTest.java
> appears to be unused. If so, then we need to remove it. If anything is
> calling it, then we need to update the naming to isWindows, or perhaps just
> change call sites to use {{Shell#WINDOWS}}.
