---------------------------------------
Summary: Implement Incremental globStatus() -> RemoteIterator class
Key: HADOOP-17275
URL: https://issues.apache.org/jira/browse/HADOOP-17275
Project: Hadoop Common
Issue Type: Sub-task
Components: fs
Affects Versions: 3.3.0
Reporter: Steve Loughran
globStatus/globber is inefficient, not incremental and doesn't provide a way to
query any IOStatistics.
Proposed:
* new IncrementalGlobber class which takes an interface to the file source
(+impls for FS and FC) which offer the incremental ops
* use incremental listStatusIncremental calls
* or, if no wildcards, full deep listFiles(recursive)
* collect IOStatistics from source ops, aggregate and serve
Potentially a lot of work...need to look carefully here
