Re: Command to delete based on column Family + rowkey
Manish,

I need to delete all the columns for a particular column family of a given
rowkey... I don't want to specify the column name (qualifier name) one by
one to delete.....

Pls let me know is there any way to delete like that...

regards,
Rams
