Assignee: Kousuke Saruta
> race condition crashes "hadoop ls -R" when directories are moved/removed
> ------------------------------------------------------------------------
>
> Key: HDFS-5546
> URL: https://issues.apache.org/jira/browse/HDFS-5546
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.2.0
> Reporter: Colin Patrick McCabe
> Assignee: Kousuke Saruta
> Priority: Minor
>
> This seems to be a rare race condition where we have a sequence of events
> like this:
> 1. org.apache.hadoop.shell.Ls calls DFS#getFileStatus on directory D.
> 2. someone deletes or moves directory D
> 3. org.apache.hadoop.shell.Ls calls PathData#getDirectoryContents(D), which
> calls DFS#listStatus(D). This throws FileNotFoundException.
> 4. ls command terminates with FNF
