"error processing template pg_hba.conf.templ" when configure a double node tableau server instance

Hi, all

I'm trying to configure a double node tableau server instance. I have successfully added this worker node(its ip and number of processes) on the configuration panel. But I received a "Worker node initialization failed" error. I've learnt in tabadmin.log that everything was OK before "error processing template pg_hba.conf.templ". Logs are pasted:

Everything is Ok

My environment is:

• Two VMs with MS server 2008. one has 4 cores and 240Gb RAM; the other has 4 cores and 64Gb RAM.
• These two VMs are not in a domain but in workgroup.
• I intalled first tableau server 9.0.8 on the primary node(the VM with bigger RAM) and then installed tableau worker software 9.0.8 on the worker node.
• I've checked Run As account and user permission of drives or repositories on both VMs. The primary node has transferred files to worker node, so I think user account permission might not be the problem.

I learned in kb that this pg_hba.conf.templ is used to configure external access to tableau database. Should I configure this file manually? Has anyone encountered the same problem? How did you get rid of this situation?

Thanks for any of your kind help!
