Eli Collins commented on HDFS-2077:
-----------------------------------
bq. Since we don't canonicalize paths anywhere, both the storage dir root and
the files within should start with the same prefix, regardless of whether there
is a symlink along the path.
Ah, didn't realize that. Yea, in this case I agree getAbsolutePath is better.
Good point btw about the stat/readlink failing after an IOE, would be good to
indicate in a comment.

> 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.
