Question 1: Is splitting the hbase region a horizontal division of the table with a capacity of 1GB, because I currently have 3 tables with very little data (2 row and 2 column family, total column: 2 per table) but is divided into 5 regions ?? That's my server test cluster. Question 2: In my main server cluster, when a regionserver dies, the load balancing set with hbase.balacer.period is 100s, then the time to load-load is 50s. After the regionserver was resurrected, after 1 day it received the region (20), the total region increased from 300 to 320. Why did that load? Question 3: I have 1 master server and 1 backup master. When I stopped regions regionserver, the master server and back up master swapped places. Why? Sorry for my bad english ... View more
