Zhiguo Wu commented on HIVE-26286:
----------------------------------
I tracked the code, It's seems because class variable _*server*_ is used before
it is initialized.
{code:java}
public Server runServer(int port)
throws Exception {
... ignore some code
!!!!!! server will be used inside createChannelConnector()
server.addConnector(createChannelConnector());
// Start the server
server.start();
!!!!!! server is initialized here
this.server = server;
return server;
}
private Connector createChannelConnector() {
ServerConnector connector;
final HttpConfiguration httpConf = new HttpConfiguration();
httpConf.setRequestHeaderSize(1024 * 64);
final HttpConnectionFactory http = new HttpConnectionFactory(httpConf);
!!!!!! server will be used here, it passes null to ServerConnector, cause NPE
if (conf.getBoolean(AppConfig.USE_SSL, false)) {
... ignore some codes
connector = new ServerConnector(server, sslContextFactory, http);
} else {
connector = new ServerConnector(server, http);
}
connector.setReuseAddress(true);
connector.setHost(conf.get(AppConfig.HOST, DEFAULT_HOST));
connector.setPort(conf.getInt(AppConfig.PORT, DEFAULT_PORT));
return connector;
}{code}
