    can you update a test to include a case where user has "NS.TBL" in default namespace and
he wants to map a view.(\"NS.TBL\")(for backward compatibility).
    ```
    desc = new HTableDescriptor(TableName.valueOf(ns+"."+table));
            desc.addFamily(new HColumnDescriptor(fam));
            admin.createTable(desc);
    
    conn.createStatement().execute("CREATE VIEW \"" + ns + "." + table + "\""
                    + "(PK VARCHAR PRIMARY KEY, " + fam + ".COL VARCHAR)");
    ```

> Firstly, I created a namespace and a table in hbase shell:

> 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.
