             Summary: [READ] Fix configuration and implementation of LevelDB-based alias maps
                 Key: HDFS-12912
                 URL: https://issues.apache.org/jira/browse/HDFS-12912
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Virajith Jalaparti


{{LevelDBFileRegionAliasMap}} fails to create the leveldb store if the directory is absent.
{{InMemoryAliasMap}} does not support reading from leveldb-based alias map created from {{LevelDBFileRegionAliasMap}} with the block id configured. Further, the configuration for these aliasmaps must be specified using local paths and not as URIs as currently shown in the documentation ({{HdfsProvidedStorage.md}}).

This JIRA is to fix these issues.
