Colin Patrick McCabe updated HDFS-4258: --------------------------------------- Resolution: Duplicate Status: Resolved (was: Patch Available) I think this JIRA / patch has gotten a bit stale, since INode IDs are already in, as well as HDFS-6294, which addressed the issues we had with moving files that were open for write. I'm marking this as a dupe of HDFS-6294. Feel free to reopen if there's something more we should do here. > Rename of Being Written Files > ----------------------------- > > Key: HDFS-4258 > URL: https://issues.apache.org/jira/browse/HDFS-4258 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs-client, namenode > Affects Versions: 3.0.0 > Reporter: Tsz Wo Nicholas Sze > Assignee: Brandon Li > Attachments: HDFS-4258.patch, HDFS-4258.patch, HDFS-4258.patch, > HDFS-4258.patch > > > When a being written file or it's ancestor directories is renamed, the path > in the file lease is also renamed. Then the writer of the file usually will > fail since the file path in the writer is not updated. > Moreover, I think there is a bug as follow: > # Client writes 0's to F_0="/foo/file" and writes 1's to F_1="/bar/file" at > the same time. > # Rename /bar to /baz > # Rename /foo to /bar > Then, writing to F_0 will fail since /foo/file does not exist anymore but > writing to F_1 may succeed since /bar/file exits as a different file. In > such case, the content of /bar/file could be partly 0's and partly 1's. -- This message was sent by Atlassian JIRA (v6.2#6252)
