Colin Patrick McCabe commented on HDFS-5582: -------------------------------------------- [~andrew.wang], I filed HDFS-5707 to fix the spacing in {{getConf}}. We could also improve some of the test whitespace in that JIRA. > hdfs getconf -excludeFile or -includeFile always failed > ------------------------------------------------------- > > Key: HDFS-5582 > URL: https://issues.apache.org/jira/browse/HDFS-5582 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.1.0-beta, 2.2.0, 2.3.0 > Reporter: Henry Hung > Assignee: sathish > Priority: Minor > Fix For: 2.3.0 > > Attachments: 00001-HDFS-5582.patch, 0002-HDFS-5582.patch > > > In hadoop-2.2.0, if you execute getconf for exclude and include file, it will > return this error message: > {code} > [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. > {code} > 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"}} > {code} > map.put(INCLUDE_FILE.getName().toLowerCase(), > new CommandHandler("DFSConfigKeys.DFS_HOSTS")); > map.put(EXCLUDE_FILE.getName().toLowerCase(), > new CommandHandler("DFSConfigKeys.DFS_HOSTS_EXCLUDE")); > {code} > A simple fix would be to remove the quote: > {code} > map.put(INCLUDE_FILE.getName().toLowerCase(), > new CommandHandler(DFSConfigKeys.DFS_HOSTS)); > map.put(EXCLUDE_FILE.getName().toLowerCase(), > new CommandHandler(DFSConfigKeys.DFS_HOSTS_EXCLUDE)); > {code} -- This message was sent by Atlassian JIRA (v6.1.5#6160)
