From v4.8.0 onwards, user can enable to map it’s schema to the namespace so that any table created with schema will be created in the corresponding namespace of HBase.
Earlier, every table (with schema or without schema) was created in default namespace.
4.8之前所有表都建在默认namespace中,用 点号 分割
phoenix 中 schema 和 table 存在 hbase default namespace 中,表名为:schema.table
4.8之后 phoenix 支持 schema 与 hbase 中 namespace 映射,但是需要额外配置 phoenix.schema.isNamespaceMappingEnabled 属性为True
