> Key: HADOOP-5193
> URL: https://issues.apache.org/jira/browse/HADOOP-5193
> Project: Hadoop Core
> Issue Type: Bug
> Components: dfs
> Affects Versions: 0.19.0
> Reporter: Konstantin Shvachko
> Assignee: Konstantin Shvachko
> Fix For: 0.19.1
>
> Attachments: EditsLength.patch
>
>
> Secondary name-node cannot complete the second phase of the checkpoint
> because getFsEditsTime() returns the mod time of {{edits.new}} rather than
> {{edits}} file.
> The difference is that {{edits}} remains unchanged during the whole
> checkpoint process an therefore can serve as an invariant. On the contrary
> {{edits.new}} is changing all the time since it is the target of the edits
> log during checkpoint. So comparison of the mod time of {{edits.new}} before
> and after checkpoint fail and name-node does not upload new image file from
> the secondary node and does not truncate edits files.
