------------------------------------------
Hi [~ikeda]
Refer this JDK bug for setName/getName thread safe fix
https://bugs.openjdk.java.net/browse/JDK-8010182
the methods setName and getName are synchronized from JDK 8. So, I think it
will not be issue with JDK8.
> DataXceiver and DFSOutputStream call Thread.setName(), which is not thread
> safe

> org.apache.hadoop.hdfs.server.datanode.DataXceiver and

> Thread.setName() is not thread safe. Thread.setName() is currently intended
