Use ToolRunner.confirmPrompt in NameNode
----------------------------------------
Key: HDFS-3249
URL: https://issues.apache.org/jira/browse/HDFS-3249
Project: Hadoop HDFS
Issue Type: Improvement
Components: name-node
Affects Versions: 2.0.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Trivial
One of the recent patches in common copied NameNode.confirmPrompt to be part of
ToolRunner, so it's available as utility code. We should now use this utility
function from within NameNode.java instead of having two copies.
