I thought this was something that we would already catch in findbugs, but maybe not?
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.6.1:compile (default-compile) on project hbase-client: Compilation failure
[ERROR] /Users/mdrob/IdeaProjects/hbase/hbase-client/src/main/java/org/apache/hadoop/hbase/shaded/protobuf/ProtobufUtil.java:[2476,5] [MissingCasesInEnumSwitch] Non-exhaustive switch; either add a default or handle the remaining cases: GLOBAL_BYPASS
[ERROR] (see http://errorprone.info/bugpattern/MissingCasesInEnumSwitch)
cc: Josh Elser, this looks like it is part of quota code. I'm happy to add a trivial patch to error on the missing case, but want somebody with more contextual knowledge to look at it.
