Subject [jira] [Commented] (HADOOP-13330) s3a large subdir delete to do listObjects() and delete() calls in parallel
Date Mon, 12 Feb 2018 12:35:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16360678#comment-16360678

Steve Loughran commented on HADOOP-13330:
-----------------------------------------

it'll be fun handling failures in this world: if one delete batch fails, you need to block
for all other outstanding deletes to complete, and update s3guard with the complete set of
successful deletes

> When doing deletes of large directories/directory trees, paged list+delete calls will
be made. It would be faster if the delete and list calls were done in parallel; the next listing
batch obtained while the current batch was being deleted.
