Virajith Jalaparti updated HDFS-12591:
--------------------------------------
Attachment: HDFS-12591-HDFS-9806.006.patch
Thanks for taking a look [~chris.douglas]. Posting a modified patch (v006)
based on the comments -- it throws an {{IllegalArgumentException}} in
{{LevelDBOptions.setConf}}, if {{DFS_PROVIDED_ALIASMAP_LEVELDB_PATH}} is not
set correctly. Also, I removed the {{@VisibleForTesting}} for {{createDB}},
made it static and added a {{boolean}} parameter to determine if the db has to
be created (when being written) or not (when being read).

> The existing work for HDFS-9806 uses an implementation of the {{FileRegion}}
> read from a csv file. This is good for testability and diagnostic purposes,
> but it is not very efficient for larger systems.
> There should be a version that is similar to the {{TextFileRegionFormat}}
> that instead uses LevelDB.
