Yes that's what scanners are good for they will return all the columns:lables combos for a row
What does the MR job stats say for rows processed for the maps and reduces?

also,

I think what we want is a way to wildcard everything after colFam1: (e.g.
colFam1:*).  Is there a way to do this in HBase?

This is assuming we dont know the column name, we want them all.

Thanks.

Yea I've got that colFam for sure in the HBase table:

{NAME => 'tableA', FAMILIES => [{NAME => 'colFam1', VERSIONS => '3',
COMPRESSION => 'NONE', LENGTH => '2147483647',
 TTL => '-1', IN_MEMORY => 'false', BLOCKCACHE => 'false'}, {NAME =>
'colFam2', VERSIONS => '3', COMPRESSION =>
 'NONE', LENGTH => '2147483647', TTL => '-1', IN_MEMORY => 'false',
BLOCKCACHE => 'false'}]}


I've been trying to play with rowcounter, and not having much luck either.

I run the command:
hadoop19/bin/hadoop org.apache.hadoop.hbase.mapred.Driver rowcounter
/home/hadoop/dev/rowcounter7 tableA colFam1:


The map/reduce finishes just like it does with my own program, but with
all part files empty in /home/hadoop/dev/rowcounter7.

Any Ideas?
