Let's assume the webtable (bigtable paper)
{code}
urlrow content anchor
language metatag ...
http://abcd.com ... anchor:http://xyz.comxyz dot com...
...
anchor:http://udanax.org udanax homepage
{code}
At this time, 'udanax.org' was evaporation from the world-wide-web.
Then we need to delete the 'anchor:http://udanax.org' of all rows.
I think this method is formal, useful, basical method.

Edward - Can you clarify your comment above? Maybe it's just a language thing,
but I really don't understand your argument for the functionality.

Bryan Duxbury commented on HADOOP-2339:

Let's specify very clearly what this issue regards.
As I understand it, the goal is to be able to delete a specific column family
and qualifier on every row in the entire table. It's important to note that the
qualifier is needed, because you can already do this essentially with ALTER
TABLE if you want to delete an entire column family. Is this correct?
If so, I'm not sure that we should offer this functionality. It will be slow,
especially if it's run as a single delete at a time in serial from the shell. I
would think that from the shell, you have the ability to empty an entire table
with TRUNCATE, or delete an entire column family with ALTER TABLE ... DROP
columnfamily, and that's probably enough. If you actually do need to delete
just a given qualified column name on every row in your table, you should write
a mapreduce job or some other highly parallel way to do that. This is in
keeping with the goal of making the shell both efficient and lean when it comes
to the functionality it supports.

Edward Yoon commented on HADOOP-2339:
-
'columnfamily', 'columnfamily:specified_qualifer' delete function is important
thing.
I'm not bothering to make a example.
Also, I thought it should be work as inter-row wise partitioned sub structre
parallelism.
But, now shell is 0.0.1 version.
Imagine the processing-speed:increment by row-count:increment 2d plots of
scanner and mapreduce,
start points of processing-speed dimension and slopes will be different.
So, I thought the cross point find algorithm for the most faster automatical
processing.
'Slow Performance' can't touch the grammar rules.

To clarify this issue, are we talking about what is essentially an ALTER TABLE
DROP COLUMN in SQL? If so, the description should be changed to reflect that.

One question: What happens if user specifies a column name that is not a column
family? I suppose in this case we should delete all cells for the specified
column? Also, I wonder if 'delete b: from udanax' shouldn't just delete column
content rather than actual column itself: i.e. disable, remove, readd,
re-enable?

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}
