Subject [jira] [Commented] (HADOOP-8131) FsShell put doesn't correctly handle a non-existent dir
Date Mon, 26 Mar 2012 18:56:28 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8131?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13238677#comment-13238677

Todd Lipcon commented on HADOOP-8131:
-------------------------------------

bq. Just to confirm: you mean a real conf key, not a cmdline flag, right?
Yep - something that could be set system-wide in core-site.xml. When users upgrade, they expect
they may have to tweak some confs for the new version, but it's harder to ask them to change
all of their shell scripts.

bq. In either case it will be a "change now or change later" scenario
Right. The idea is that they would have some warning (a full major version) before their code
stops working. Our general policy is to only make the breaking change after having the deprecated
support for a full major version -- in which case it would go away in 0.24.0.

bq. Would this bring back the issue of left out _temporary dirs? (MAPREDUCE-1272)
I would think the MR task would be using the new non-deprecated API which doesn't recursively
create parents.
