作为一个大数据从业者来说, hadoop, hbase, hive, spark, storm这是都是应用得比较成熟的系统了，虽然维护性差，版本兼容性弱，但是依然坚挺着。。。
hive仅仅只是一个客户端，主流spark on yarn模式中spark也是个客户端，对于storm来说, 被 twitter捐给apache后，主人离职移交权利，活生生成了弃子一颗。故本人亦从storm流式平台转向了KSQL流式平台...
所以我们常用的大数据集群系统只有hadoop + hbase
hadoop分为两块组块, 分布式文件系统hdfs以及资源管理器yarn。
这里我们介绍的是hbase数据库，建立在hadoop hdfs模块之上，基于LSM存储引擎读写高性能的列式NOSQL数据库。目前已成为大数据服务的重要一环。
这里选择的版本是HADOOP 3.0，为什么呢？
因为hadoop 2.0的兼容性太弱，当前hbase跟spark都在积极拥抱hadoop 3.0.
其它也没有太多要介绍的，那么就开始正式的主题吧。
搭建hbase-2.1 on hadoop-3.1.1的集群
由于精力有限，hadoop及hbase均没有加入HA功能，后续将会补充进来。
分为以下四个过程:
- 创建虚拟机-createvm.sh
- 打包依赖-package.sh
- 部署集群-deploy.sh
- 启动集群-start.sh
- 测试集群
项目路径: https://github.com/clojurians-org/my-env
代码路径:run.sh.d/hbase-example/{createvm.sh, package.sh, deploy.sh, start.sh}
第0步: 创建虚拟机-createvm.sh
[larluo@larluo-nixos:~/my-env]$ cat run.sh.d/hbase-example/createvm.sh
set -e
my=$(cd -P -- "$(dirname -- "${BASH_SOURCE-$0}")" > /dev/null && pwd -P) && cd $my/../..
echo -e "\n==== bash nix.sh create-vm nixos-hbase-001" && bash nix.sh create-vm nixos-hbase-001
echo -e "\n==== bash nix.sh create-vm nixos-hbase-002" && bash nix.sh create-vm nixos-hbase-002
echo -e "\n==== bash nix.sh create-vm nixos-hbase-003" && bash nix.sh create-vm nixos-hbase-003

成功创建三台虚拟机: 192.168.56.101, 192.168.56.102, 192.168.56.103
第1步: 打包依赖-package.sh
[larluo@larluo-nixos:~/my-env]$ cat run.sh.d/hbase-example/package.sh
set -e
my=$(cd -P -- "$(dirname -- "${BASH_SOURCE-$0}")" > /dev/null && pwd -P) && cd $my/../..
echo -e "\n==== bash nix.sh build tgz.hbase-2.1.0" && bash nix.sh build tgz.hbase-2.1.0
echo -e "\n==== bash nix.sh export tgz.nix-2.0.4" && bash nix.sh export tgz.nix-2.0.4
echo -e "\n==== bash nix.sh export nix.rsync-3.1.3" && bash nix.sh export nix.rsync-3.1.3
echo -e "\n==== bash nix.sh export nix.gettext-0.19.8.1" && bash nix.sh export nix.gettext-0.19.8.1
echo -e "\n==== bash nix.sh export nix.openjdk-8u172b11" && bash nix.sh export nix.openjdk-8u172b11
echo -e "\n==== bash nix.sh export nix.zookeeper-3.4.13" && bash nix.sh export nix.zookeeper-3.4.13
echo -e "\n==== bash nix.sh export nix.hadoop-3.1.1" && bash nix.sh export nix.hadoop-3.1.1
由于hbase默认是hadoop 2的版本，故hbase on hadoop3需定制编译，打包时会自动调用。
这里由于时间关系，没有采用nix构建，直接使用mvn打包，后续可能会优化..
[larluo@larluo-nixos:~/my-env]$ cat nix.conf/hbase-2.1.0/build.sh
mvn package -Dhadoop.profile=3.0 -Dhadoop-three.version=3.1.1 -DskipTests assembly:single
这里我们除了安装nix, rsync, gettext基本工具外，添加了jdk,zookeeper,hadoop的nix软件包，最后调用hbase构建过程.

第2步. 部署集群-deploy.sh
[larluo@larluo-nixos:~/my-env]$ cat run.sh.d/hbase-example/deploy.sh
set -e
my=$(cd -P -- "$(dirname -- "${BASH_SOURCE-$0}")" > /dev/null && pwd -P) && cd $my/../..
echo -e "\n==== bash nix.sh create-user 192.168.56.101" && bash nix.sh create-user 192.168.56.101
echo -e "\n==== bash nix.sh create-user 192.168.56.102" && bash nix.sh create-user 192.168.56.102
echo -e "\n==== bash nix.sh create-user 192.168.56.103" && bash nix.sh create-user 192.168.56.103

echo -e "\n==== bash nix.sh install 192.168.56.102 nix.gettext-0.19.8.1" && bash nix.sh install 192.168.56.102 nix.gettext-0.19.8.1
echo -e "\n==== bash nix.sh install 192.168.56.103 nix.gettext-0.19.8.1" && bash nix.sh install 192.168.56.103 nix.gettext-0.19.8.1
echo -e "\n==== bash nix.sh install 192.168.56.101 nix.openjdk-8u172b11" && bash nix.sh install 192.168.56.101 nix.openjdk-8u172b11
echo -e "\n==== bash nix.sh install 192.168.56.102 nix.openjdk-8u172b11" && bash nix.sh install 192.168.56.102 nix.openjdk-8u172b11
echo -e "\n==== bash nix.sh install 192.168.56.103 nix.openjdk-8u172b11" && bash nix.sh install 192.168.56.103 nix.openjdk-8u172b11
echo -e "\n==== bash nix.sh install 192.168.56.101 nix.zookeeper-3.4.13" && bash nix.sh install 192.168.56.101 nix.zookeeper-3.4.13
echo -e "\n==== bash nix.sh install 192.168.56.102 nix.zookeeper-3.4.13" && bash nix.sh install 192.168.56.102 nix.zookeeper-3.4.13
echo -e "\n==== bash nix.sh install 192.168.56.103 nix.zookeeper-3.4.13" && bash nix.sh install 192.168.56.103 nix.zookeeper-3.4.13
echo -e "\n==== bash nix.sh install 192.168.56.101 nix.hadoop-3.1.1" && bash nix.sh install 192.168.56.101 nix.hadoop-3.1.1
echo -e "\n==== bash nix.sh install 192.168.56.102 nix.hadoop-3.1.1" && bash nix.sh install 192.168.56.102 nix.hadoop-3.1.1

echo -e "\n==== bash nix.sh import 192.168.56.103 tgz.hbase-2.1.0" && bash nix.sh import 192.168.56.103 tgz.hbase-2.1.0
这个过程基本上与package打包一一对应，将软件包分发至各个服务器
