Todd Lipcon updated HDFS-2077:
------------------------------
Attachment: hdfs-2077.txt
Attached patch with following changes:
- storage inspector now uses the new FileUtil.listFiles to avoid a
NullPointerException in the case that the storage is inaccessible.
- NNStorage now has a function to report an error based on a file path. If the
file path is within one of the storage dirs, it gets marked as failed.
- TransferFsImage now uses that new feature to notify storage of failure to
open streams, and only fails the request if *all* of the streams fail to open.
> 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.
