rongtong 6a9e84f113 [ISSUE #10651] bump DLedger to 0.3.3.4 (maintenance line) (#10958)
* chore: bump DLedger to 0.3.3.4 (maintenance line)

Update the DLedger dependency from 0.3.2 to 0.3.3.4, the latest
release on the 0.3.x maintenance line published on Maven Central.
The 0.3.3.4 release is API-compatible with 0.3.2 and only carries
dependency hygiene fixes (aligning fastjson2 and excluding fastjson1
from its rocketmq-remoting transitive path).

Also update the Bazel WORKSPACE artifact coordinate to keep the two
build systems in sync.

* chore: fully remove fastjson1 from the build

DLedger 0.3.3.4 already excludes com.alibaba:fastjson from its
rocketmq-remoting dependency and its bytecode only references
fastjson2, but rocketmq still declared fastjson1 itself, so it kept
leaking onto every module compile classpath through rocketmq-common.

- drop the com.alibaba:fastjson property and dependencyManagement
  entry from the root pom
- drop the unused com.alibaba:fastjson dependency from rocketmq-common
  (no main source imports com.alibaba.fastjson.*)
- drop the fastjson1 pin from WORKSPACE and the fastjson1 dep from the
  remoting test target in remoting/BUILD.bazel
- migrate RemotingSerializableCompatTest to fastjson2: use the
  fastjson2 JSONField annotation (which is what the protocol classes
  actually carry) and round trip through RemotingSerializable instead
  of com.alibaba.fastjson.JSON

fastjson1 wire-format coverage is retained by the frozen fastjson1
payload already asserted in testCompatibilityCheckWithBitSet.

* fix(bazel): exclude rocketmq-remoting from coursier resolution

dledger 0.3.3.4 depends on rocketmq-remoting:5.5.0, which Coursier
fetches from Maven Central. That artifact transitively brings
grpc-netty-shaded:1.53.0 with a strict [1.53.0] range on grpc-core,
conflicting with the WORKSPACE-declared grpc 1.47.0 artifacts.

Since rocketmq-remoting is built from source in this repo (//remoting),
exclude it from external resolution — matching what PR #10947 already
does for the DLedger 0.4.x line.

Apache RocketMQ is a distributed messaging and streaming platform with low latency, high performance and reliability, trillion-level capacity and flexible scalability.

It offers a variety of features:

  • Messaging patterns including publish/subscribe, request/reply and streaming
  • Financial grade transactional message
  • Built-in fault tolerance and high availability configuration options based on DLedger Controller
  • Built-in message tracing capability, also supports opentracing
  • Versatile big-data and streaming ecosystem integration
  • Message retroactivity by time or offset
  • Reliable FIFO and strict ordered messaging in the same queue
  • Efficient pull and push consumption model
  • Million-level message accumulation capacity in a single queue
  • Multiple messaging protocols like gRPC, MQTT, JMS and OpenMessaging
  • Flexible distributed scale-out deployment architecture
  • Lightning-fast batch message exchange system
  • Various message filter mechanics such as SQL and Tag
  • Docker images for isolated testing and cloud isolated clusters
  • Feature-rich administrative dashboard for configuration, metrics and monitoring
  • Authentication and authorization
  • Free open source connectors, for both sources and sinks
  • Lightweight real-time computing

Quick Start

This paragraph guides you through steps of installing RocketMQ in different ways. For local development and testing, only one instance will be created for each component.

Run RocketMQ locally

RocketMQ runs on all major operating systems and requires only a Java JDK version 8 or higher to be installed. To check, run java -version:

$ java -version
java version "1.8.0_121"

For Windows users, click here to download the 5.5.0 RocketMQ binary release, unpack it to your local disk, such as D:\rocketmq. For macOS and Linux users, execute following commands:

# Download release from the Apache mirror
$ wget https://dist.apache.org/repos/dist/release/rocketmq/5.5.0/rocketmq-all-5.5.0-bin-release.zip

# Unpack the release
$ unzip rocketmq-all-5.5.0-bin-release.zip

Prepare a terminal and change to the extracted bin directory:

$ cd rocketmq-all-5.5.0-bin-release/bin

1) Start NameServer

NameServer will be listening at 0.0.0.0:9876, make sure that the port is not used by others on the local machine, and then do as follows.

For macOS and Linux users:

### start Name Server
$ nohup sh mqnamesrv &

### check whether Name Server is successfully started
$ tail -f ~/logs/rocketmqlogs/namesrv.log
The Name Server boot success...

For Windows users, you need to set environment variables first:

  • From the desktop, right click the Computer icon.
  • Choose Properties from the context menu.
  • Click the Advanced system settings link.
  • Click Environment Variables.
  • Add Environment ROCKETMQ_HOME="D:\rocketmq".

Then change directory to rocketmq, type and run:

$ mqnamesrv.cmd
The Name Server boot success...

2) Start Broker

For macOS and Linux users:

### start Broker
$ nohup sh mqbroker -n localhost:9876 &

### check whether Broker is successfully started, eg: Broker's IP is 192.168.1.2, Broker's name is broker-a
$ tail -f ~/logs/rocketmqlogs/broker.log
The broker[broker-a, 192.168.1.2:10911] boot success...

For Windows users:

$ mqbroker.cmd -n localhost:9876
The broker[broker-a, 192.168.1.2:10911] boot success...

Run RocketMQ in Docker

You can run RocketMQ on your own machine within Docker containers, host network will be used to expose listening port in the container.

1) Start NameServer

$ docker run -it --net=host apache/rocketmq ./mqnamesrv

2) Start Broker

$ docker run -it --net=host --mount type=bind,source=/tmp/store,target=/home/rocketmq/store apache/rocketmq ./mqbroker -n localhost:9876

Run RocketMQ in Kubernetes

You can also run a RocketMQ cluster within a Kubernetes cluster using RocketMQ Operator. Before your operations, make sure that kubectl and related kubeconfig file installed on your machine.

1) Install CRDs

### install CRDs
$ git clone https://github.com/apache/rocketmq-operator
$ cd rocketmq-operator && make deploy

### check whether CRDs are successfully installed
$ kubectl get crd | grep rocketmq.apache.org
brokers.rocketmq.apache.org                 2022-05-12T09:23:18Z
consoles.rocketmq.apache.org                2022-05-12T09:23:19Z
nameservices.rocketmq.apache.org            2022-05-12T09:23:18Z
topictransfers.rocketmq.apache.org          2022-05-12T09:23:19Z

### check whether operator is running
$ kubectl get pods | grep rocketmq-operator
rocketmq-operator-6f65c77c49-8hwmj   1/1     Running   0          93s

2) Create Cluster Instance

### create RocketMQ cluster resource
$ cd example && kubectl create -f rocketmq_v1alpha1_rocketmq_cluster.yaml

### check whether cluster resources are running
$ kubectl get sts
NAME                 READY   AGE
broker-0-master      1/1     107m
broker-0-replica-1   1/1     107m
name-service         1/1     107m
