Date Mon, 21 Dec 2015 23:36:46 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-12473?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mingliang Liu updated HADOOP-12473:
-----------------------------------
    Description: In {{CopyMapper::handleFailure}}, the mapper handles failure and will ignore
it if no it's config key is on. Ignoring failures option {{-i}} should be mutually exclusive
with the {{-atomic}} option otherwise an incomplete dir is eligible for commit defeating the
purpose.  (was: In {{CopyMapper::handleFailure}}, the mapper handles failure and will ignore
it if no it's config key is on. Ignoring failures should be mutually exclusive with the atomic
option otherwise an incomplete dir is eligible for commit defeating the purpose.)
