Todd Lipcon commented on HDFS-2077:
-----------------------------------
just found a good bug in this while doing some fault testing... in
reportErrorOnFile, it will mis-ascribe an error sometimes if one namenode
directory is a prefix of the other... eg if the storage dirs are /data/name and
/data/name2, it will ascribe an error in /data/name2/... to /data/name.
> 1073: address checkpoint upload when one of the storage dirs is failed

> This JIRA addresses the following case:
> - NN is running with 2 storage dirs
> - 1 of the dirs fails
> - 2NN makes a checkpoint
> Currently, if GetImageServlet fails to open _any_ of the local files to
> receive a checkpoint, it will fail the entire checkpoint upload process.
> Instead, it should continue to receive checkpoints in the non-failed
> directories.
