Allen Wittenauer resolved HADOOP-5889. -------------------------------------- Resolution: Incomplete I'm just going to close this as stale, esp given s3 allegedly works. > Allow writing to output directories that exist, as long as they are empty > ------------------------------------------------------------------------- > > Key: HADOOP-5889 > URL: https://issues.apache.org/jira/browse/HADOOP-5889 > Project: Hadoop Common > Issue Type: Improvement > Components: fs > Affects Versions: 0.18.3 > Reporter: Ian Nowland > Attachments: HADOOP-5889-0.patch > > > The current behavior in FileOutputFormat.checkOutputSpecs is to fail if the > path specified by mapred.output.dir exists at the start of the job. This is > to protect from accidentally overwriting existing data. There seems no harm > then in slightly relaxing this check to allow the case for the output to > exist if it is an empty directory. > At a minimum this would allow outputting to the root of S3N buckets, which is > currently impossible (https://issues.apache.org/jira/browse/HADOOP-5805). -- This message was sent by Atlassian JIRA (v6.2#6252)
