Is there a way to just ask for column names in a row to get just a column names list (and not the entire <column<String,String>>). I am using Hector.
I have a row of valueless columns (whose column names are keys to another set of rows) & I wish to retrieve a list of those column names and send it in another query to retrieve the corresponding rows pointed by each of those columns. Now if I do a normal query I get list of columns like: List <Column <String, String>> but I would need to pass to another query as just column names list like: List <String> Is there any method in java which could transforms this list in a better way, rather than iterating over each column and extracting its name into another list ? What would be the best way to do such queries?
