--------------------------------------

Thanks [~misty].
I think we have to introduce the new API modifyFamily of HTableDescriptor, how 
about to change the code to
{code}
    // Update existing CF
    HColumnDescriptor newColumn = new HColumnDescriptor(CF_DEFAULT);
    newColumn.setCompactionCompressionType(Algorithm.GZ);
    newColumn.setMaxVersions(HConstants.ALL_VERSIONS);
    table_assetmeta.modifyFamily(newColumn)
    admin.modifyTable(tableName, table_assetmeta);
{code}

> In the new implementation of HTableDescriptor, updating an existing CF 
> doesn't use the addFamily any more(An IllegalArgumentException is thrown in 
> such a case.), the new API modifyFamily is used instead.
> We need to update the ref guide (currently Example 10.2) to show "update an 
> existing CF" with the new API modifyFamily in master.
