> For replication_scope, only two values are meaningful:
> {code} 
>   public static final int REPLICATION_SCOPE_LOCAL = 0;
>   public static final int REPLICATION_SCOPE_GLOBAL = 1;
> {code} 
> However, there is no checking for that, so currently user can set it to any integer value. And all non-zero value will be treated as 1(GLOBAL). 
> This jira is to add a checking in HColumnDescriptor#setScope() so that only 0 and 1 will be accept during create_table or alter_table. 
> In the future, we can leverage replication_scope to store for info. For example: 
> -1: A columnfam is replicated from another cluster in MASTER_SLAVE setup (i.e readonly)
> 2 : A columnfam is set MASTER_MASTER
> Probably a major improve JIRA is needed for the future usage. It will be good to ensure the scope value at this moment.
