Steve Loughran, Hi, thanks for the reply, I've tested what you have suggested,
and encountered some problem: When I try with protobuf=2.6.1 using -D option I
failed to build trunk branch due to:
2019-07-10 09:43:03.803715 | ubuntu-xenial-arm64 | [ERROR] Failed to execute

Maybe this is due to that grpc requires protobuf 3.6.1?
(https://github.com/apache/hadoop/blob/993dc8726b7d40ac832ae3e23b64e8541b62c4bd/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-csi/pom.xml#L29)
And when I try to use protobuf 3.6.1 directly, something else failed to build:
[ERROR] Failed to execute goal

project hadoop-hdfs: Compilation failure

incompatible types:
org.apache.hadoop.hdfs.server.namenode.FsImageProto.FileSummary cannot be
converted to com.google.protobuf.GeneratedMessage[m

seems due to this part of the code is not compatiable for protobuf v3?
Any suggestion on these?

> Standard protobuf 2.5.0 does not work properly on many platforms. (See, for
> example, https://gist.github.com/BennettSmith/7111094 ). In order for us to
> avoid crazy work arounds in the build environment and the fact that 2.5.0 is
> starting to slowly disappear as a standard install-able package for even
> Linux/x86, we need to either upgrade or self bundle or something else.
