Dmitriy V. Ryaboy commented on PIG-1946:
----------------------------------------
Spaces are legal:
hbase(main):011:0> put 'dropme', 'id1', 'columns:foo bar', 'value'
0 row(s) in 0.0060 seconds
hbase(main):012:0> scan 'dropme'
ROW COLUMN+CELL
id1 column=columns:foo bar,
timestamp=1307395400107, value=value
So I think that means 2 flags are needed: -d (delimiter, space by default) and
-ignoreTrailingCommas (true by default, turn off to force trailing commas to be
treated as part of the column name)
> HBaseStorage constructor syntax is error prone

> Using {{HBaseStorage}} like so seems like a reasonable thing to do, but it
> will yield unexpected results:
> {code}
> STORE result INTO 'hbase://foo' USING
> org.apache.pig.backend.hadoop.hbase.HBaseStorage(
> 'info:first_name, info:last_name');
> {code}
> The problem us that a column named {{info:first_name,}} will be created, with
> the trailing comma included. I've had numerous developers get tripped up on
> this issue since everywhere else in Pig variables are separated by commas, so
> I propose we fix it.
> I propose we trim leading/trailing commas from column names, but I'm open to
> other ideas.
> Also should we accept column names that are comman-delimited without spaces?
