> Thanks @szetszwo for updating the patch. i think We need to change the parsing logic applyTransaction call in ContainerStateMachine as well because the integration test failures are related here:
> `Caused by: org.apache.ratis.protocol.StateMachineException: org.apache.ratis.thirdparty.com.google.protobuf.InvalidProtocolBufferException from Server bad6dc6c-9418-448d-ad47-5f803b5e863b@group-6CEFB1F28D35: Protocol message contained an invalid tag (zero). at org.apache.ratis.thirdparty.com.google.protobuf.InvalidProtocolBufferException.invalidTag(InvalidProtocolBufferException.java:105) at org.apache.ratis.thirdparty.com.google.protobuf.CodedInputStream$ArrayDecoder.readTag(CodedInputStream.java:646) at org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos$ContainerCommandRequestProto.<init>(ContainerProtos.java:2692) at org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos$ContainerCommandRequestProto.<init>(ContainerProtos.java:2655) at org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos$ContainerCommandRequestProto$1.parsePartialFrom(ContainerProtos.java:7272) at org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos$ContainerCommandRequestProto$1.parsePartialFrom(ContainerProtos.java:7267) at org.apache.ratis.thirdparty.com.google.protobuf.AbstractParser.parsePartialFrom(AbstractParser.java:105) at org.apache.ratis.thirdparty.com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:125) at org.apache.ratis.thirdparty.com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:130) at org.apache.ratis.thirdparty.com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:49) at org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos$ContainerCommandRequestProto.parseFrom(ContainerProtos.java:4110) at org.apache.hadoop.ozone.container.common.transport.server.ratis.ContainerStateMachine.getContainerCommandRequestProto(ContainerStateMachine.java:383) at org.apache.hadoop.ozone.container.common.transport.server.ratis.ContainerStateMachine.applyTransaction(ContainerStateMachine.java:708) at org.apache.ratis.server.impl.RaftServerImpl.applyLogToStateMachine(RaftServerImpl.java:1274) at org.apache.ratis.server.impl.StateMachineUpdater.applyLog(StateMachineUpdater.java:224) at org.apache.ratis.server.impl.StateMachineUpdater.run(StateMachineUpdater.java:165)`
Oops, need one more fix (a4ae0852f818f6a49403b784790b1babb3df71f5) as shown below since it calls request.getMessage().getContent() again in startTransaction(..).
