Hi,
While trying to run the airavata server, I have got the following error message:

I ran the following two scripts:
go to 
          
/home/pga/master-deployment/api-orchestrator/apache-airavata-server-<version>-SNAPSHOT/bin
 and run ./airavata-server-start.sh -d api-orch
go to 
         
/home/pga/master-deployment/gfac-instance/apache-airavata-server-<version>-SNAPSHOT/bin
 and run ./airavata-server-start.sh -d gfac

Thanks.
