Yiqun Lin created HDFS-13957: -------------------------------- Summary: Fix incorrect option used in description of InMemoryAliasMap Key: HDFS-13957 URL: https://issues.apache.org/jira/browse/HDFS-13957 Project: Hadoop HDFS Issue Type: Bug Components: documentation Affects Versions: 3.1.1 Reporter: Yiqun Lin
The incorrect option was used in description of InMemoryAliasMap. {noformat} This is a LevelDB-based alias map that runs as a separate server in Namenode. The alias map itself can be created using the fs2img tool using the option -Ddfs.provided.aliasmap.leveldb.path=file:///path/to/leveldb/map/dingos.db -o org.apache.hadoop.hdfs.server.common.blockaliasmap.impl.LevelDBFileRegionAliasMap as in the example above. {noformat} Here -o should be -b, -o is specified for output directory of generated fsimage. -b is for block output class. The right usage showed in the doc: {noformat} hadoop org.apache.hadoop.hdfs.server.namenode.FileSystemImage \ -Ddfs.provided.aliasmap.leveldb.path=/path/to/leveldb/map/dingos.db \ -b org.apache.hadoop.hdfs.server.common.blockaliasmap.impl.LevelDBFileRegionAliasMap \ -o file:///tmp/name \ -u CustomResolver \ hdfs://enfield/projects/ywqmd/incandenza {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
