Definition

Appends replicable tables/column families to the specified 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.

NOTE

This command does not remove the previously defined tables/column families from the replication peer configuration (unlike set_peer_tableCFs).

Usage

append_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

Examples

Successful table appending

Without column families

hbase(main):037:0> show_peer_tableCFs '1'
default.articles
Took 0.0077 seconds
=> "default.articles"
hbase(main):042:0> append_peer_tableCFs '1', {'table10' => []}

With column families
