多集群之间的备份使用CopyTable
参考 http://hbase.apache.org/book/ops_mgt.html#copytable
CopyTable is a utility that can copy part or of all of a table, either to the same cluster or another cluster. The usage is as follows:
$ bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable [--starttime=X] [--endtime=Y] [--new.name=NEW] [--peer.adr=ADR] tablename
Options:
starttime Beginning of the time range. Without endtime means starttime to forever.
endtime End of the time range. Without endtime means starttime to forever.
versions Number of cell versions to copy.
new.name New table's name.
peer.adr Address of the peer cluster given in the format hbase.zookeeper.quorum:hbase.zookeeper.client.port:zookeeper.znode.parent
families Comma-separated list of ColumnFamilies to copy.
all.cells Also copy delete markers and uncollected deleted cells (advanced option).
Args:
tablename Name of table to copy.
Example of copying 'TestTable' to a cluster that uses replication for a 1 hour window:
$ bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable
--starttime=1265875194289 --endtime=1265878794289
--peer.adr=server1,server2,server3:2181:/hbase TestTable
