Masatake Iwasaki updated HDFS-8063:
-----------------------------------
Attachment: HDFS-8063.001.patch
Shutting down MiniDFSCluster assures no spans arrived any more. I merged
testWriteWithoutTraceHooks and testReadWithoutTraceHooks in order to reduce the
number of MiniDFSCluster startup as far as possible. I also removed code
duplication.

>
> Tests in TestTracing sometimes fails, especially on slow machine. The cause
> is that spans is possible to arrive at receiver after
> {{assertSpanNamesFound}} passed and
> {{SetSpanReceiver.SetHolder.spans.clear()}} is called for next test case.
