如何使用phoenix操作hbase数据)
这篇文章将为大家详细讲解有关如何使用phoenix操作hbase数据)，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
1.下载安装phoenix(版本与hbase对应)
[root@node1 ~]# wget http://mirrors.shu.edu.cn/apache/phoenix/apache-phoenix-5.0.0-HBase-2.0/bin/apache-phoenix-5.0.0-HBase-2.0-bin.tar.gz
[root@node1 ~]# tar xvf apache-phoenix-5.0.0-HBase-2.0-bin.tar.gz -C /opt/
[root@node1 opt]# mv apache-phoenix-5.0.0-HBase-2.0-bin/ phoenix-5.0.0
2.考贝jar包
[root@node1 opt]# cd phoenix-5.0.0/
[root@node1 phoenix-5.0.0]# cp -a phoenix-5.0.0-HBase-2.0-server.jar phoenix-core-5.0.0-HBase-2.0.jar /opt/hbase-2.0.4/lib/
[root@node1 phoenix-5.0.0]# scp phoenix-5.0.0-HBase-2.0-server.jar phoenix-core-5.0.0-HBase-2.0.jar node2:/opt/hbase-2.0.4/lib/ --考贝到其它节点
[root@node1 phoenix-5.0.0]# cd /opt/hbase-2.0.4/conf/
[root@node1 conf]# cp -a hbase-site.xml /opt/phoenix-5.0.0/bin/
[root@node1 conf]# cd /opt/hadoop-2.8.5/etc/hadoop/
[root@node1 hadoop]# cp hdfs-site.xml core-site.xml /opt/phoenix-5.0.0/bin/
3.重启hbase服务
[root@node1 conf]# stop-hbase.sh
[root@node1 conf]# start-hbase.sh
4.登陆hbase和phoenix
[root@node1 phoenix-5.0.0]# hbase shell
