Question regarding data location in hdfs after hbase restarts

[Tao Xie]

hi, all
I set hdfs replica=1 when running hbase. And DN and RS co-exists on each
slave node. So the data in the regions managed by RS will be stored on its
local data node, rite?
But when I restart hbase and hbase client does gets on RS, datanode will
read data from remote data nodes. Does that mean when RS restart, the
regions are re-arranged? If so, will hbase is clever enough to re-adjust the
regions? I'm not clear about the behind mechanism so anyone can give me some
explanations? Thanks.
