Description

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.
