You probably executed 120k next() RPC against your server, unless you enabled scanner caching.
(On a related note, we should probably not default this to 1, but something more sensible, like 10 or 100).

Subject: HBase vs. HDFS
I'm trying to get familiarized with HBase and one thing I noticed is that
reads seem to very slow. I just tried doing a "scan 'my_table'" to get 120K
records and it took about 50 seconds to print it all out.
In contrast "hadoop fs -cat my_file.csv" where my_file.csv has 120K lines
completed in under a second.
Is that possible? Am I missing something about HBase reads?
