[jira] [Created] (HADOOP-8295) ToolRunner.confirmPrompt spins if stdin goes away

ToolRunner.confirmPrompt spins if stdin goes away
-------------------------------------------------

                 Key: HADOOP-8295
                 URL: https://issues.apache.org/jira/browse/HADOOP-8295
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Todd Lipcon
            Priority: Minor


Currently, ToolRunner.confirmPrompt treats a "-1" response to its System.in.read() call the same as \n or \r. So, if stdin goes away, it can cause the JVM to spin in a loop. Instead, it should treat a -1 result as a "n" response.
