I've basically set it up such that the HBase master is running on the same machine as the name node, and the region servers are running on the other 4 machines as slaves. I'm trying to populate a single table with about 10GB of data via a map/reduce job, and I'm noticing that the region servers are running out of memory. Any pointers on what could be going on here? Thanks, Ryan
