Description

Prior to HDFS-1826, doUpgrade() would fail if any of the storage directories failed to successfully write the new fsimage or edits files.
Now it appears to "succeed" even if some or all of the individual directories fail.

There is some discussion about whether doUpgrade() should have some fault tolerance, but for now make it fail on any single storage directory failure, as before.
