> libhdfs++: Implement parallel find with wildcards tool
> ------------------------------------------------------

> Key: HDFS-10679
> URL: https://issues.apache.org/jira/browse/HDFS-10679
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs-client
> Reporter: Anatoli Shein

>
> The find tool will issue the GetListing namenode operation on a given
> directory, and filter the results using posix globbing library.
> If the recursive option is selected, for each returned entry that is a
> directory the tool will issue another asynchronous call GetListing and repeat
> the result processing in a recursive fashion.
> One implementation issue that needs to be addressed is the way how results
> are returned back to the user: we can either buffer the results and return
> them to the user in bulk, or we can return results continuously as they
> arrive. While buffering would be an easier solution, returning results as
> they arrive would be more beneficial to the user in terms of performance,
> since the result processing can start as soon as the first results arrive
> without any delay. In order to do that we need the user to use a loop to
> process arriving results, and we need to send a special message back to the
> user when the search is over.
