HBase 良好的分布式架构设计为海量数据的快速存储、随机访问提供了可能,基于数据副本机制和分区机制可以轻松实现在线扩容、缩容和数据容灾,是大数据领域中 Key-Value 数据结构存储最常用的数据库方案。
一、概述
HBase 是一个面向列式存储的分布式数据库,其设计思想来源于 Google 的 BigTable 论文。HBase 底层存储基于 HDFS 实现,集群的管理基于 ZooKeeper 实现。HBase 良好的分布式架构设计为海量数据的快速存储、随机访问提供了可能,基于数据副本机制和分区机制可以轻松实现在线扩容、缩容和数据容灾,是大数据领域中 Key-Value 数据结构存储最常用的数据库方案。
- 官方文档:https://hbase.apache.org/book.html
- GitHub地址:https://github.com/apache/hbase
- 关于更多hbase的介绍,也可以参考我这篇文章:列式存储的分布式数据库——HBase(环境部署),
- 因为hbase依赖于HDFS存储,关于HDFS容器化部署可以参考我以下文章:【云原生】Hadoop on k8s 环境部署
- 但是生产环境一般使用高可用的Hadoop的,关于高可用部署可参考我这篇文章:【云原生】Hadoop HA on k8s 环境部署
- hbase依赖于Zookeeper,zookeeper容器化部署可以参考:【云原生】zookeeper + kafka on k8s 环境部署
二、开始编排部署(非高可用HDFS)
地址:https://artifacthub.io/packages/helm/hbase/hbase
1)下载chart 包
helm repo add hbase https://itboy87.github.io/bigdata-charts/
# hbase version 2.4.13
helm pull hbase/hbase --version 0.1.7
2)构建镜像
在下面连接hadoop高可用会重新构建镜像,这里就不重新构建镜像了,只是把远程的包推送到本地harbor仓库
docker pull ghcr.io/fleeksoft/hbase/hbase-base:2.4.13.2
# tag
docker tag ghcr.io/fleeksoft/hbase/hbase-base:2.4.13.2 myharbor.com/bigdata/hbase-base:2.4.13.2
# push
docker push myharbor.com/bigdata/hbase-base:2.4.13.2
3)修改yaml编排(非高可用HDFS)
image:
repository: myharbor.com/bigdata/hbase-base
tag: 2.4.13.2
pullPolicy: IfNotPresent
...
conf:
hadoopUserName: admin
hbaseSite:
hbase.rootdir: "hdfs://hadoop-hadoop-hdfs-nn.hadoop:9000/hbase"
hbase.zookeeper.quorum: "zookeeper.zookeeper:2181"
...
hbase:
master:
replicas: 2
regionServer:
replicas: 2
# 禁用内部的hadoop
hadoop:
enabled: false
# 禁用内部的zookeeper
zookeeper:
enabled: false
- hbase/templates/hbase-configmap.yaml
if [ ` `.`Values`.`hadoop`.`enabled ` = true ];then
NAMENODE_URL={{- printf "http://%s-hadoop-hdfs-nn:9870/index.html" .Release.Name }}
else
hadoop_url={{ index .Values.conf.hbaseSite "hbase.rootdir" }}
hadoop_url=`echo $hadoop_url|awk -F '/' '{print $3}'|awk -F':' '{print $1}'`
NAMENODE_URL=http://${hadoop_url}:9870/index.html
fi
4)开始部署
# 先检查语法
helm lint ./hbase
# 开始安装
helm install hbase ./hbase -n hbase --create-namespace
NOTES
NAME: hbase
LAST DEPLOYED: Sat Nov 5 15:44:14 2022
NAMESPACE: hbase
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
1. You can get an HBASE Shell by running this command:
kubectl exec -n hbase -it hbase-hbase-master-0 -- hbase shell
2. Inspect hbase master service ports with:
kubectl exec -n hbase describe service hbase-hbase-master
3. Create a port-forward to the hbase manager UI:
kubectl port-forward -n hbase svc/hbase-hbase-master 16010:16010
Then open the ui in your browser:
open http://localhost:16010
4. Create a port-forward to the hbase thrift manager UI:
kubectl port-forward -n hbase svc/hbase-hbase-master 9095:9095
Then open the ui in your browser:
open http://localhost:9095
HDFS
查看
kubectl get pods,svc -n hbase -owide
5)测试验证
测试主备切换,重启当前active master pod
kubectl delete pod hbase-hbase-master-0 -n hbase
主备能正常切换
6)卸载
helm uninstall hbase -n hbase
# delete ns
kubectl delete ns hbase --force
三、开始编排部署(高可用 HDFS)
1)下载chart 包
helm repo add hbase https://itboy87.github.io/bigdata-charts/
# hbase version 2.4.13
helm pull hbase/hbase --version 0.1.7
2)构建镜像
这里是基于上面的镜像进行构建,只是把hadoop打包到镜像中,主要用的hadoop配置文件是core-site.yaml,hdfs-site.yaml
Dockerfile
FROM myharbor.com/bigdata/hbase-base:2.4.13.2
RUN mkdir -p /opt/apache
ENV HADOOP_VERSION=3.3.2
ADD hadoop-${HADOOP_VERSION}.tar.gz /opt/apache
ENV HADOOP_HOME=/opt/apache/hadoop
RUN ln -s /opt/apache/hadoop-${HADOOP_VERSION} $HADOOP_HOME
ENV HADOOP_CONF_DIR=${HADOOP_HOME}/et/hadoop
ENV PATH=${HADOOP_HOME}/bin:$PATH
开始构建
docker build -t myharbor.com/bigdata/hbase-hdfs-ha:2.4.13.2 . --no-cache
### 参数解释
# -t:指定镜像名称
# . :当前目录Dockerfile
# -f:指定Dockerfile路径
# --no-cache:不缓存
# 推送到harbor
docker push myharbor.com/bigdata/hbase-hdfs-ha:2.4.13.2
3)修改配置
- hbase-hdfs-ha/values.yaml
image:
repository: myharbor.com/bigdata/hbase-hdfs-ha
tag: 2.4.13.2
pullPolicy: IfNotPresent
...
conf:
hadoopUserName: admin
hbaseSite:
hbase.rootdir: "hdfs://myhdfs/hbase"
hbase.zookeeper.quorum: "zookeeper.zookeeper:2181"
- hbase-hdfs-ha/templates/hbase-configmap.yaml
if [ {{ .Values.hadoop.enabled }} = true ];then
NAMENODE_URL={{- printf "http://%s-hadoop-hdfs-nn:9870/index.html" .Release.Name }}
else
NAMENODE_URL=http://hadoop-ha-hadoop-hdfs-nn-1.hadoop-ha:9870:9870/index.html
