Review comment:
HBASE-18698 moves Driver to be the main-class in hbase-mapreduce jar rather
than hbase-server jar. hbase-server jar has no Main-Class in MANIFEST.MF, so
when I use hadoop jar hbase-server-VERSION.jar completebulkload, hadoop cannot
find the main class in hbase-server jar, and throws exception like this:
```
Exception in thread "main" java.lang.ClassNotFoundException: completebulkload
at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:348)
at org.apache.hadoop.util.RunJar.run(RunJar.java:311)
at org.apache.hadoop.util.RunJar.main(RunJar.java:232)
```
According to HBASE-18698, it adds `Main-Class:
org/apache/hadoop/hbase/mapreduce/Driver` in hbase-mapreduce jar, so the
correct way to use completebulkload is hadoop jar hbase-mapreduce-VERSION.jar
completebulkload.
