Event table from Hazelcast

I am using below execution plan to populate my hazelcast backed event table. Problem is, how can I reuse this existing hazelcast backed event table from another execution plan ?

It is a followup question for another similar question.

@Import('users:1.0.0')
define stream users (meta_name string, correlation_id int);

@from(eventtable = 'hazelcast', cluster.name = 'cluster_a', cluster.password = 'pass@cluster_a')
define table UserTable (name string, id int) ;

from users
select meta_name as name, correlation_id as id
insert OVERWRITE UserTable
  on UserTable.id == id;

You can use same collection.name in both execution plans. You don't need to use cluster.name and cluster.password. Refer to following example;

Execution Plan 1

@Plan:name('TestIn')

@Import('dataIn:1.0.0')
define stream dataIn (id int, name string);

@from(eventtable = 'hazelcast', collection.name='hzTable')
define table hzTable (id int, name string);

from dataIn
insert into hzTable;

Execution Plan 2

@Plan:name('TestOut')

@Export('dataOut:1.0.0')
define stream dataOut (id int, name string);

@from(eventtable = 'hazelcast', collection.name='hzTable')
define table hzTable (id int, name string);

define trigger periodicTrigger at every 2 sec;

from periodicTrigger join hzTable
select hzTable.id as id, hzTable.name as name
insert into dataOut;
