Replication across three or more clusters
When configuring replication among three or more clusters, Cloudera recommends to enable
KEEP_DELETED_CELLS
on column families in the destination cluster, where
REPLICATION_SCOPE=1
in the source cluster.
The following commands show how to enable this configuration using HBase Shell.
- On the source
cluster:
create 't1',{NAME=>'f1', REPLICATION_SCOPE=>1}
- On the destination
cluster:
create 't1',{NAME=>'f1', KEEP_DELETED_CELLS=>'true'}
