---------------------------------------

             Summary: distcp numListstatusThreads option doesn't get to -delete scan
                 Key: HADOOP-15384
                 URL: https://issues.apache.org/jira/browse/HADOOP-15384
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: tools/distcp
    Affects Versions: 3.1.0
            Reporter: Steve Loughran
            Assignee: Steve Loughran


The distcp {{numListstatusThreads}} option isn't used when configuring the GlobbedCopyListing
used in {{CopyComitter.deleteMissing()}}

This means that for large scans of object stores, performance is significantly worse.

Fix: pass the option down from the task conf
