Date Tue, 27 Mar 2012 13:32:15 GMT

to the column family.. is it so or it is just synactical error??

[default@CMDCv99] create column family status
...         with comparator = AsciiType
...         and column_metadata =
...         [{
...             column_name : Test,
...             validation_class : IntegerType,
...             index_type : 0,
...             index_name : IdxName},
...         {
...             column_name : 'other name',
...             validation_class : CounterColumnType
...         }];
