I use Hbase-0.94 and CDH-4.3.1 When RegionServer read data from loca datanode, if local datanode is dead, the local datanode is add to deadNodes, and RegionServer read data from remote datanode. But when local datanode is become live, RegionServer still read data from remote datanode, that reduces the performance of RegionServer. We need to on way that remove local datanode from deadNodes when the local datanode is become live.
I can do it, please everybody give some advises. Thanks, LiuLei
