Hbase跨集群同步数据

增量同步

add_peer '5', CLUSTER_KEY => "192.168.1.1,192.168.1.2,192.168.1.3:2181:/hbase", STATE => "ENABLED"

set_peer_tableCFs '5', { "jfrcs:graph" => ["e", "f", "g", "h", "i", "l", "m", "s", "t"] }

enable_table_replication 'jfrcs:graph'

快照全量

1.源头他那快照
snapshot 'jfrcs:graph','jfrcs_graph_snp'

2.源头发到目标
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot jfrcs_graph_snp -copy-to hdfs://ip:8020/hbase -mappers 32 -bandwidth 250

3.目标节点恢复快照
clone_snapshot 'jfrcs_graph_snp', 'jfrcs:graph'
