                 URL: https://issues.apache.org/jira/browse/HADOOP-2385
             Project: Hadoop
          Issue Type: Improvement
          Components: dfs
    Affects Versions: 0.16.0

Configuration parameters should be fully validated before name nodes or data nodes begin service.

Required parameters must be present.
Required and optional parameters must have values of proper type and range.
Undefined parameters must not be present.

(I was recently observing some confusion whose root cause was a mis-spelled parameter.)
