> If we run testDisableAndEnableReplication, we will get the following error message.

> The critical code is shown below.
> {code}
>     admin1.disableTableReplication(tableName);
>     HTableDescriptor table = admin1.getTableDescriptor(tableName);
>     for (HColumnDescriptor fam : table.getColumnFamilies()) {
>       assertEquals(fam.getScope(), HConstants.REPLICATION_SCOPE_LOCAL);
>     }
>     table = admin2.getTableDescriptor(tableName);
>     for (HColumnDescriptor fam : table.getColumnFamilies()) {
>       assertEquals(fam.getScope(), HConstants.REPLICATION_SCOPE_LOCAL);
>     }
> {code}
> Is HTD got from admin2 affected by admin1? I don't think so. We should remove the related
assertion.
