We don't do checkstyle as part of default "mvn install" since it takes significant amount of time (~90sec) and slows builds and development. We only need it for pre-commits.
This module has proto files used by core. These protos overlap with protos that are used by coprocessor endpoints (CPEP) in the module hbase-protocol. So core versions have a different name, the generated classes are relocated -- i.e. shaded -- to a new location; they are moved from org.apache.hadoop.hbase.* to org.apache.hadoop.hbase.shaded.
