java.rmi.notboundexception

While start log stash with :
docker exec -e JAVA_HOME=/home/test/program/jdk1.8.0_65 -i --user test hadoop11 bash -c "bash /home/test/logstash-6.5.4/startup.sh" >/dev/null 2>&1 &

We always meet java.rmi.notboundexception, the exception is thrown by client code that test wehether RPC server is started.
if we start RPC first and start logstash later, this probelm would not happen.
if you kown the reason, plese answer it at this link
