-----------------------------------------------
Summary: Yarn Service AM listens on all IP's on the machine
Key: YARN-10439
URL: https://issues.apache.org/jira/browse/YARN-10439
Project: Hadoop YARN
Issue Type: Bug
Components: security, yarn-native-services
Reporter: D M Murali Krishna Reddy
Assignee: D M Murali Krishna Reddy
In ClientAMService.java, rpc server is created without passing hostname, due to
which the client listens on 0.0.0.0, which is a bad practise.
{{InetSocketAddress address = {color:#cc7832}new
{color}InetSocketAddress({color:#6897bb}0{color}){color:#cc7832};
{color}{color:#9876aa}server {color}=
rpc.getServer(ClientAMProtocol.{color:#cc7832}class, this,
{color}address{color:#cc7832}, {color}conf{color:#cc7832},
{color}
{color:#9876aa}context{color}.{color:#9876aa}secretManager{color}{color:#cc7832},
{color}{color:#6897bb}1{color}){color:#cc7832};{color}}}
Also, a new configuration must be added similar to
"yarn.app.mapreduce.am.job.client.port-range", so that client can configure
port range for yarn service AM to bind.
