Read data by sourcing regardless of a local lim

Dear

I want to explain the customer's request.

Here is an execution server with a lim daemon.

On this execution server, the customer wants to send queries to another cluster.
(In this case, the LSF_LIM_PORT of both clusters is the same, because it is a multicluster environment)

But by the logic below,
the local lim exists, means there is a lim daemon running with the LSF_LIM_PORT.
lsid==>read lim port from lsf.conf==>connect Local LIM by UDP==>read information from its memory data==>the information in memory data updates when local lim restarts or configuration file changes.

Even if sourcing another cluster's LSF environment,
Since the port is the same, data from the running lim is read, so the desired cluster information cannot be read.

I understand that a host cannot belong to more than one cluster.
Requirements for resource sharing between 2 clusters
A host cannot belong to more than one cluster.

He want the query to be processed by sourcing regardless of the local lim, so I'd like to discuss it with you.

Best regards
JMC

    Allowing this would negatively impact security, allowing a user to point commands at a random external server.
    An alternative approach would be to use the restful api and authenticate against which cluster you want to collect informationfrom.
