     Manually checking the set of Keys that look like packages we relocate:

      cat `find . \( -name '*Keys.java' -o -name '*KeysPublic.java' \) -a -path '*/src/main/*'`  | grep -E "\"(io\.|org\.|com\.|net\.)" | grep -v "^package" | grep -v "^import" | grep -v "\"org.apache.hadoop"

     Manually check the set of shaded artifacts to see if the Keys constants have been relocated:

     for clazz in `find . \( -name '*Keys.java' -o -name '*KeysPublic.java' \) -a -path '*/src/main/*'`; do
       clazz=${clazz#*src/main/java/}
       clazz="${clazz%.java}"
