This reverts commit 5b58d11c91cbbc2f73e4252088c97df12a49ff87. I accidentally applied this as myself instead of as Bryan. Reverting it to apply the patch properly.
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.
