Masatake Iwasaki updated HDFS-8063:
-----------------------------------
Attachment: HDFS-8063.002.patch
Tests in the current TestTracing could be done in single test method in order
to reduce the number of starting MiniDFSCluster. Reading with tracing which
causes the problem should be done in the last as did in 002.
