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 is automatically generated by JIRA.
