> {{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.
