Anatoli Shein updated HDFS-10679: --------------------------------- Status: Patch Available (was: Open) > 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 > Assignee: 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
