hbase的练习和phonenix的使用

1.进入hbase的操作

./hbase shell

list 展示 所有表格

此时hdfs上可以查询到hbase上设置的t1

 

java代码连接zookeeper控制hbase代码

可以看到运行create和insert后插入的数据

hbase的具体操作命令

https://www.cnblogs.com/cxzdy/p/5583239.html

查询命令：

phonenix:

1.解压phoenix-4.5.2-HBase-1.1-bin.tar

2.将jar放入hbase集群的各个节点中去

   cp /home/phoenix-4.5.2-HBase-1.1-bin/phoenix-core-4.5.2-HBase-1.1.jar /home//hbase-1.1.3/lib/

   scp /home/phoenix-4.5.2-HBase-1.1-bin/phoenix-core-4.5.2-HBase-1.1.jar root@node2:/home//hbase-1.1.3/lib/

  scp /home/phoenix-4.5.2-HBase-1.1-bin/phoenix-core-4.5.2-HBase-1.1.jar root@node3:/home//hbase-1.1.3/lib/

3.重启hbase

4../stop-hbase.sh

5../start-hbase.sh

6.连接使用phonenix

   ./sqlline.py node1

成功使用phonenix来使用sql操作hbase;完美
