> I was writing 300GiB data to my Hbase table user_info, the table I created by default having only one region. When the writing was going I saw one region became two regions and more late on it became 8 regions. But my confusion is that the 8 regions were kept in the same RegionServer. Why Hbase didn't split the regions to different RegionServer. btw, I had 10 physical RegionsServers in my Hbase cluster, and the region size I set is 20GiB, Thanks!
