[jira] Updated: (MAPREDUCE-2234) If Localizer can't create task log directory, it should fail on the spot

["Todd Lipcon (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2234?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Todd Lipcon updated MAPREDUCE-2234:
-----------------------------------

    Attachment: mapreduce-2234.txt

Now with more unit tests, plus some new unit tests for behavior with regard to permissions of mapred.local.dirs during startup.

I'd be interested in people's opinions on something: if some (or all) of the mapred.local.dirs are unwritable when the TT starts up, should it shut itself down?

> Currently, it simply emits a warning. Then, when the taskjvm.sh tries to pipe its output into this directory, it fails with a strange error code like "exit code: 1" which is not intuitive to ops. Instead it should simply throw an exception at initialization time rather than attempting to run the task.
