Definition

Sets all replicable tables/column families for the replication relationship (peer). Remember the following restrictions:

The REPLICATE_ALL flag should have the false value in the replication peer configuration (see set_peer_replicate_all).
If the peer configuration already contains some namespace (added via append_peer_namespaces or set_peer_namespaces), then setting its tables with this command is not allowed.
If you need to clear included tables/column families, run the current command with an empty dictionary as the second input parameter. You can also use the remove_peer_tableCFs command.

CAUTION

This command removes the previously defined tables/column families from the replication peer configuration (unlike append_peer_tableCFs).

Usage

set_peer_tableCFs '<peer_id>',
                  {'[<namespace_name>:]<table_name>' => <column_families_array[]>[,...]}

Arguments
Parameter	Description
peer_id	A unique identifier of the replication peer. Should not contain hyphens
namespace_name	A namespace name
table_name	A table name
column_families_array	An array of strings specified in the format `'<column_family>'`, where `<column_family>` — a column family name

  Set the replicable table-cf config for the specified peer.

  Note:
  1. The replicate_all flag need to be false when set the replicable table-cfs.
  2. Can't set a table to table-cfs config if it's namespace already was in
     namespaces config of this peer.

  Examples:

    # set table-cfs config is null, then the namespaces config decide which
    # table to be replicated.
    hbase> set_peer_tableCFs '1'
    # set table / table-cf to be replicable for a peer, for a table without
    # an explicit column-family list, all replicable column-families (with
    # replication_scope == 1) will be replicated
    hbase> set_peer_tableCFs '2',
     { "ns1:table1" => [],
     "ns2:table2" => ["cf1", "cf2"],
     "ns3:table3" => ["cfA", "cfB"]}
