 for more. The complaint you see is something like the following:
 `Cause: java.lang.RuntimeException: Failed construction of Master: class org.apache.hadoop.hbase.master.HMasterorg.apache.hadoop.hbase.shaded.io.netty.channel.epoll.`

+If running unit tests and you run into the above message, add the system property

+Again the trailing period in the value above is intended.

 The `hbase-thirdparty` project has groupid of `org.apache.hbase.thirdparty`.
