Hello, I am a newbie to Hive, but I'm already quite familiar with Hadoop/HBase. I must appreciate the whole project and especially the new integration with HBase, which is what we really need. :)
So back to the problem, I got Hive running with HBase, it works really nice, gets data from HBase, computes something and returns results. But even when I run it on a large table with hundreds of regions, it splits data only into 2 maps, which means only 2 task trackers running on a 10 node cluster. When I run similar task written in Java+MapReduce and fire it up, it splits input into hundreds of maps and the computation is nicely distributed. Is it some misconfiguration or why the Hive's InputSplit gives me only 2 maps? Regards, Martin Fiala
