Protobuf 2.5 JAR is no longer needed at runtime. The option common.protobuf.scope defines whether the protobuf 2.5.0 dependency is marked as provided or not. * New package org.apache.hadoop.ipc.internal for internal only protobuf classes ...with a ShadedProtobufHelper in there which has shaded protobuf refs only, so guaranteed not to need protobuf-2.5 on the CP * All uses of org.apache.hadoop.ipc.ProtobufHelper have been replaced by uses of org.apache.hadoop.ipc.internal.ShadedProtobufHelper * The scope of protobuf-2.5 is set by the option common.protobuf2.scope In this patch is it is still "compile" * There is explicit reference to it in modules where it may be needed. * The maven scope of the dependency can be set with the common.protobuf2.scope option. It can be set to "provided" in a build: -Dcommon.protobuf2.scope=provided * Add new ipc(callable) method to catch and convert shaded protobuf exceptions raised during invocation of the supplied lambda expression * This is adopted in the code where the migration is not traumatically over-complex. RouterAdminProtocolTranslatorPB is left alone for this reason. Contributed by Steve Loughran |
