    can you include isNamespaceMapped as table name with schema can also be in default namespace.
    ```

> Firstly, I created a namespace and a table in hbase shell:
> {code}
> hbase> create_namespace "NS"
> hbase> create "NS:TBL", "CF"
> {code}
> After that, I tried to create a phoenix view for this existing hbase table in phoenix-sqlline:
> {code}
> phoenix> CREATE VIEW ns.tbl (pk VARCHAR PRIMARY KEY, cf.col VARCHAR);
> {code}
> However, I encountered the following error and I was not able to create the view:
> {code}
> org.apache.phoenix.schema.ReadOnlyTableException: ERROR 505 (42000): Table is read only.
