> When you issue an "ALTER TABLE" for a global index to add a column, Phoenix throws a SQLException, but the HBase metadata for the global index table is still modified.
> Steps to reproduce:
>  * Create the base data table: 
> {code:java}
> create table if not exists z_base_table (id INTEGER not null primary key, host VARCHAR(10), flag boolean);{code}
>  * Create a global index on top of this table: 
> {code:java}
> create index global_z_index on z_base_table(HOST);{code}
>  * Add a column to the global index table:
> {code:java}
> alter table global_z_index add cf1.age INTEGER;{code}
> This will throw an exception in Phoenix, but HBase metadata for the global index table is still modified. Stack trace:
> {noformat}
> Error: ERROR 1010 (42M01): Not allowed to mutate table. Cannot add/drop column referenced by VIEW columnName=GLOBAL_Z_INDEX (state=42M01,code=1010)
>  java.sql.SQLException: ERROR 1010 (42M01): Not allowed to mutate table. Cannot add/drop column referenced by VIEW columnName=GLOBAL_Z_INDEX
