Review Comment:
   It could, but we normally run it using the `hbase` script, so that we get CP 
built, in which case, shipping slf4j classes within the hbck2 jar was causing 
below problems to me:
   
   `SLF4J: Class path contains multiple SLF4J bindings.
   SLF4J: Found binding in 
[jar:file:/root/hbase-3.0.0-alpha-3-SNAPSHOT/hbase-hbck2-1.3.0-SNAPSHOT.jar!/org/slf4j/impl/StaticLoggerBinder.class]
   SLF4J: Found binding in 
[jar:file:/root/hbase-3.0.0-alpha-3-SNAPSHOT/lib/client-facing-thirdparty/log4j-slf4j-impl-2.17.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
   SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an 
explanation.
   SLF4J: Actual binding is of type 
[org.apache.logging.slf4j.Log4jLoggerFactory]
