How do you look that? > 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 > Priority: Minor > Attachments: HDFS-5546.1.patch > > > 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 -- This message was sent by Atlassian JIRA (v6.1#6144)
