Managing request in spring microservices with multiple instances of a single service

I have a java project and I am trying to scale my project so want to spin up 3 instance of a single microservice.

But I have an issue

to explain

From UI when user logs in, every 10sec a api request(for the specific user) goes to backend which gives the status of spring batch job (either running or not running for a particular user who has logged in). This works fine with only 1 instance.

but when I have 3 instances (instance 1, 2 & 3) of the same application,

say first request at 10sec goes to instance 1 and job is running for the logged in user - it returns job is running. - correct second request at 20sec goes to instance 2, since no job is running in instance 2 (job is running in instance 1) it return no job is running - incorrect third request at 30sec goes to instance 3, since no job is running in instance 3 (job is running in instance 3) it return no job is running - incorrect

How do I make sure to get "job is running" as the status till the job in instance 1 gets over.

I am using spring microservices

please help in on this

Thanks in advance

Need to get job is running till job finishes in instance 1 for the particular user, for every api request
