Hi, I am using CDH3U0 Hadoop and Hbase.
I know that HDFS automatically replicates data to multiple data nodes so that when a couple of data nodes fail, the user won't lose any data. I am currently using replication factor of 3. Now in Hbase, I know there is some experimental replication service, but I am not using it. I thought that since HDFS already does replication, Hbase wouldn't need additional replication. Am I right on this? So my question would be: Given that I am using HDFS replication and not using Hbase replication, if a couple of regionservers fail, am I still able to access all the data I have stored before? I would appreciate any help. Thanks. Ed
