[jboss-jira] [JBoss JIRA] Resolved: (JBCACHE-817) Remove all calls to InetAddress.getHostName() (causes reverse DNS lookup)

Remove all calls to InetAddress.getHostName() (causes reverse DNS lookup) ------------------------------------------------------------------------- Key: JBCACHE-817 URL: http://jira.jboss.com/jira/browse/JBCACHE-817 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering Environment: JBoss 4.0.4 Reporter: Michael Newcomb Assigned To: Manik Surtani Priority: Minor Any call to InetAddress.getHostName() will cause a reverse DNS lookup. If DNS is not configured, can cause slow startup/join times between JBoss clusters. The most notable is in ClusterNode.java: public ClusterNode(IpAddress jgAddress) { if (jgAddress.getAdditionalData() == null) { this.id = jgAddress.getIpAddress().getHostAddress() + ":" + jgAddress.getPort(); } else { this.id = new String(jgAddress.getAdditionalData()); } this.originalJGAddress = jgAddress; StringBuffer sb = new StringBuffer(); java.net.InetAddress jgIPAddr = jgAddress.getIpAddress(); if (jgIPAddr == null) sb.append("<null>"); else { if (jgIPAddr.isMulticastAddress()) sb.append(jgIPAddr.getHostAddress()); else ----->>>> sb.append(getShortName(jgIPAddr.getHostName())); } sb.append(":" + jgAddress.getPort()); this.jgId = sb.toString(); } The following: if (jgIPAddr.isMulticastAddress()) sb.append(jgIPAddr.getHostAddress()); else sb.append(getShortName(jgIPAddr.getHostName())); should be replaced with: sb.append(jgIPAddr.getHostAddress()); I am currently trying to configure our machine for reverse DNS lookup to see if that at least solves the slow lookup problem.
