Description

When running a simple Job to read data from HBase 2 I got this exception, so it seems not all needed classes are included in `hbase-shaded-client`

java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/shaded/org/mortbay/jetty/nio/SelectChannelConnector
at com.example.hbase.HBaseIOTest.beforeClass(HBaseIOTest.java:79)
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.shaded.org.mortbay.jetty.nio.SelectChannelConnector
at com.example.hbase.HBaseIOTest.beforeClass(HBaseIOTest.java:79

If I replace the dependency with just `hbase-client` everything works correctly.
I created an external repo to test this in case someone may want to take a look.
