Subject [jira] [Commented] (HADOOP-12358) FSShell should prompt before deleting directories bigger than a configured size
Date Fri, 28 Aug 2015 00:50:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14717842#comment-14717842

Arpit Agarwal commented on HADOOP-12358:
----------------------------------------

bq. If automation really wants to delete that many blocks, then what? How does it override
if the only option to do so forces a prompt?
The administrator should consider this potential breakage before enabling it. We should make
it explicit in the documentation.

bq. We could add "-y, --yes, or --assume-yes" to automatic yes to prompts so that delete run
non-interactively.
We have seen some administrators routinely pass {{–skipTrash}} which leads to these situations.
IMO if we add {{--yes}} or similar they will just start including that as well.

> We have seen many cases with customers deleting data inadvertently with -skipTrash. The
FSShell should prompt user if the size of the data or the number of files being deleted is
bigger than a threshold even though -skipTrash is being used.
