Phoenix 启动报错：
Error: ERROR 726 (43M10): Inconsistent namespace mapping properties. Cannot initiate connection as SYSTEM:CATALOG is found but client does not have phoenix.schema.isNamespaceMappingEnabled enabled (state=43M10,code=726)

解决方法如下：
1、删除hbase和phoenix conf目录下的hbase-site.xml中关于命名空间启用的设置。

2、重启hbase，进入hbase shell

3、修改hbase中表SYSTEM:CATALOG名为SYSTEM.CATALOG
1）disable 'SYSTEM:CATALOG'
2）snapshot 'SYSTEM:CATALOG','cata_tableSnapshot’

3）clone_snapshot 'cata_tableSnapshot', 'SYSTEM.CATALOG'

4）drop 'SYSTEM:CATALOG'

4、重启phoenix
cd /opt/phoenix/bin/
