I am trying to create a database using JDBC.
I am working in a beowulf cluster, where there is one master node, and
many client nodes.

Right now I want to create JDBC on the master node, and three client nodes.

The postmaster is running on all four of them, the postmaster is using
/tmp/data directory. I modified the ppostgres.conf to set tcpip=true, and
added the ip address to pg_hba.conf file for this to work on the master

But this does not work on the client nodes. i added the ip pf the client
nodes to pg_hba.conf file too. But still it gives me an error as though
there is no IP added:
org.postgresql.util.PSQLException: A connection error has occurred:
org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host
"", user "kashif", database "gayathkash34"

        at org.postgresql.Driver.connect(
        at java.sql.DriverManager.getConnection(
        at java.sql.DriverManager.getConnection(
        at JavaJdbc.main(

I added the IP: to the pg_hba.conf file.

Could you help with this?
