[jboss-jira] [JBoss JIRA] Moved: (JBAS-6879) pullNewDeployments in FarmMemberService is buggy

pullNewDeployments in FarmMemberService is buggy ------------------------------------------------ Key: JBAS-6879 URL: https://jira.jboss.org/jira/browse/JBAS-6879 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering Environment: jboss 4.2.2 onwards Reporter: sachin mishra Assignee: Brian Stansberry pullNewDeployments method in FarmMemberService is not working correctly during startup where there are more than 1 nodes in the cluster. Currently newly started cluster will always pull the files from the coordinator node as the call to DeployedURL du = (DeployedURL)parentDUMap.get(depName); will always return null on startup. Steps to reproduce: 1. create 2 or more nodes in 1 cluster 2. deploy app Test.war in the cluster 3. restart 1 of the nodes and you will see that this node is pulling the Test.war. Test.war hasn't changed therefore no need to pull it. This is currently causing a lot of issues in our server as we have lots of apps ( over 100) deployed and are quite big in size , therefore pull all the files at startup causes the server to become available after a very long time. Possible Fix; @Override protected void pullNewDeployments(HAPartition partition, HashMap farmed) { if(ServiceMBean.STARTING == getState()){ if(doInit){ init(); doInit = false; } }else{ logger.info("using pullNewDeployments on FarmMemberService as we are not in starting state... " ); super.pullNewDeployments(partition, farmed); return; } Iterator it = farmed.keySet().iterator(); String parentName= null; File destFile = null; while (it.hasNext()) { String depName = (String)it.next(); Date last = (Date)farmed.get(depName); DeployedURL du = (DeployedURL)parentDUMap.get(depName); int indexofParentName = depName.indexOf('/'); parentName= depName.substring(0, indexofParentName); String child = depName.substring(indexofParentName+1, depName.length()); File parentFolder = findParent(parentName); if(parentFolder == null){ IllegalStateException stateException = new IllegalStateException("Can't find the farmed folder " + parentName); logger.error(stateException,stateException); throw stateException; } destFile = new File(parentFolder,child); Date localDeployedDate = new Date(destFile.lastModified()); logger.info("parentname=" + parentName + " destfile= " +destFile.getAbsolutePath() + " isexist=" + destFile.exists() + " local mode date=" + localDeployedDate + " remote deploy date=" + last); if(destFile.exists() && !localDeployedDate.before(last)){ logger.info(" no need to pull " + depName + " from remote server as the timestamps are same"); }else{ logger.info(" going to pull " +depName + " from remote server....."); pullRemoteFile(new File(depName), parentName); } } } private void init() { try{ HAPartition lHAPartition = null; if (mClusterPartition != null) { lHAPartition = mClusterPartition.getHAPartition(); } if (lHAPartition == null) { // Old style config with PartitionName was used -- have to // look up the partition in JMX lHAPartition = (HAPartition) getServer().getAttribute( mClusterPartitionName, "HAPartition" ); } mFileTransfer = new ClusterFileTransfer(lHAPartition, buildParentFolderMapping()); logger.warn("Created mFileTransfer successfully"); }catch(Exception e){ logger.error("Error Starting ClusterMemberService ",e); } }
