> [~daryn] has noticed that Invoking hadoop ls on HAR is taking too much of
> time.
> The har system has multiple deficiencies that significantly impacted
> performance:
> # Parsing the master index references ranges within the archive index. Each
> range required re-opening the hdfs input stream and seeking to the same
> location where it previously stopped.
> # Listing a har stats the archive index for every "directory". The per-call
> cache used a unique key for each stat, rendering the cache useless and
> significantly increasing memory pressure.
> # Determining the children of a directory scans the entire archive contents
> and filters out children. The cached metadata already stores the exact child
> list.
> # Globbing a har's contents resulted in unnecessary stats for every leaf path.
