Hi Henry, Good finding!
You can file a ticket in Jira and post a patch if you willing to do it. Thanks and Regards, Vinayakumar B From: Henry Hung [mailto:[email protected]] Sent: 29 November 2013 07:37 To: [email protected] Subject: hdfs getconf -excludeFile or -includeFile always failed HI All, In hadoop-2.2.0, if you execute getconf for exclude and include file, it will return this error message: [hadoop@fphd1 hadoop-2.2.0]$ bin/hdfs getconf -excludeFile Configuration DFSConfigKeys.DFS_HOSTS_EXCLUDE is missing. [hadoop@fphd1 hadoop-2.2.0]$ bin/hdfs getconf -includeFile Configuration DFSConfigKeys.DFS_HOSTS is missing. I found out the root cause is very simple, it's because the source code of org/apache/hadoop/hdfs/tools/GetConf.java hard coded it to "DFSConfigKeys.DFS_HOSTS" and "DFSConfigKeys.DFS_HOSTS_EXCLUDE" map.put(INCLUDE_FILE.getName().toLowerCase(), new CommandHandler("DFSConfigKeys.DFS_HOSTS")); map.put(EXCLUDE_FILE.getName().toLowerCase(), new CommandHandler("DFSConfigKeys.DFS_HOSTS_EXCLUDE")); A simple fix would be to remove the quote: map.put(INCLUDE_FILE.getName().toLowerCase(), new CommandHandler(DFSConfigKeys.DFS_HOSTS)); map.put(EXCLUDE_FILE.getName().toLowerCase(), new CommandHandler(DFSConfigKeys.DFS_HOSTS_EXCLUDE)); I don't know if someone already post this issue in JIRA. If not, I will be glad to open a request.
