I tried this out from scratch and was able to build Ozone on my m1 macbook
by only patching protobuf 2.5. Here are the steps I followed:
- Rename my current `.m2` directory to `.m2.old` so it is not used
- Clone the apache Ozone repo fresh into a new directory with the latest
master branch checked out.
- Attempt to build: `mvn -DskipTests=true -Dmaven.javadoc.skip=true
--threads 2.0C clean package`
- Fails trying to get protobuf 2.5
- Do the following steps, which are a mix of @smengcl's older
[guide](https://gist.github.com/smengcl/6a269f44d909ef9245a9ad8c7c6d41e0#file-ozone-m1-md)
and the steps in this PR:
```
PROTOBUF_VERSION="2.5.0"
curl -LO
https://github.com/protocolbuffers/protobuf/releases/download/v2.5.0/protobuf-2.5.0.tar.gz
tar xzf protobuf-2.5.0.tar.gz
cd protobuf-${PROTOBUF_VERSION}
vim src/google/protobuf/stubs/platform_macros.h
# Append the following after line 59:
#elif defined(__arm64__)
#define GOOGLE_PROTOBUF_ARCH_ARM 1
#define GOOGLE_PROTOBUF_ARCH_64_BIT 1
./configure --disable-shared
make -j
mvn install:install-file -DgroupId=com.google.protobuf -DartifactId=protoc
-Dversion=2.5.0 -Dclassifier=osx-aarch_64 -Dpackaging=exe -Dfile=src/protoc
# It failed without the following command since I'm using Maven 3.9.1
mv
$HOME/.m2/repository/com/google/protobuf/protoc/${PROTOBUF_VERSION}/protoc-${PROTOBUF_VERSION}-osx-aarch_64
$HOME/.m2/repository/com/google/protobuf/protoc/${PROTOBUF_VERSION}/protoc-${PROTOBUF_VERSION}-osx-aarch_64.exe
```
- Build again: `mvn -DskipTests=true -Dmaven.javadoc.skip=true --threads
2.0C clean package`
- This time success
@fmorg-git do you recall if you had to do any extra setup related to docker
images for running acceptance tests locally? In my local setup I had built an
arm version of the ozone-runner image since it used to be that one was not
available, but it looks like we have those on [docker
hub](https://hub.docker.com/r/apache/ozone-runner/tags) now.
Also, if proto 2.5 is the only thing requiring manual intervention, let's
add a note in these docs that it is for hadoop 2 support, in case people are
wondering why they need to deal with such an old version.
