Edward Yoon commented on HADOOP-2339:
-------------------------------------
ugh... It seems troublesome...
*hql > DELETE columnA: FROM table;*
In this case, only "columnA:" should be deleted.
{code}
columnA: ----> to be deleted
columnA:a
columnA:b
{code}
....
And then, how can i delete all columns in columnfamily?
I'd like to use the deleteColumn() method to drop the *ColumnFamily*
{code}
DROP TABLE table_name;
DROP COLUMNFAMILY columnfamily_name;
{code}
> [Hbase Shell] Delete command with no WHERE clause
