Hi All. There is confused understanding about region-regionser locality.
from the current document , http://hbase.apache.org/book/regions.arch.html 9.7.3. Region-RegionServer Locality Over time, Region-RegionServer locality is achieved via HDFS block replication. The HDFS client does the following by default when choosing locations to write replicas: First replica is written to local node Second replica is written to another node in same rack Third replica is written to a node in another rack (if sufficient nodes) but, my understanding is different HDFS write blocks for replica first, local node second, another node in another rack third, random another node in same rack need to be changed? or am I missing something?
