Modified compared to main branch to deprecate obviated MasterObserver interface methods instead of remove them. Signed-off-by: Sean Busbey <busbey@apache.org> (cherry picked from commit c5ca191921cad9100fb47aa57348571b3ddc06ad) Conflicts: hbase-client/src/main/java/org/apache/hadoop/hbase/client/AdminOverAsyncAdmin.java hbase-server/src/test/java/org/apache/hadoop/hbase/rsgroup/VerifyingRSGroupAdmin.java hbase-server/src/test/java/org/apache/hadoop/hbase/security/access/TestWithDisabledAuthorization.java
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.
