> changes to the hbase shell:
> > alter 'table', {NAME => 'cf', VERSIONS => 3}
> This command will try to find the column family named 'cf' at first.
> If has, it will modifyColumn, if not, add the column
> > alter 'table', {NAME => 'cf', 'method' => 'delete'}
> This command will delete the column family named 'cf'.
> To achieve this goal, i also add a method to the HBaseAdmin.java
> public TableDescriptor getTableDescriptor(byte[] tableName);
