-----------------------------------
+1 looks good. Thanks for the explanations!
> HDFS-1826 made FSImage.doUpgrade() too fault-tolerant

> Key: HDFS-1955
> URL: https://issues.apache.org/jira/browse/HDFS-1955
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: name-node
> Affects Versions: 0.22.0, 0.23.0
> Reporter: Matt Foley

>
> 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.
