HBase block replication
Does HBase replicate blocks similar to how HDFS replicates for
redundancy reasons? Where can this be configured or is it already
managed by the hdfs-site.xml dfs.replication property?
Thanks

Hi there-
Look at the Hbase files on the HDFS file system...
http://hbase.apache.org/book.html#trouble.namenode.hbase.objects
... and run some checks like 'fsck'

How can this be tested and or verified? Would/should it show up under
'Online Regions' on the region server status page
(http://hbase-region1:60030/rs-status)?
Thanks
