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).

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? Thanks, Joni
