[Ted Yu (JIRA)]

Ted Yu created YARN-2117:
----------------------------

             Summary: Close of Reader in 
TimelineAuthenticationFilterInitializer#initFilter() should be enclosed in 
finally block
                 Key: YARN-2117
                 URL: https://issues.apache.org/jira/browse/YARN-2117
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


Here is related code:
{code}
        Reader reader = new FileReader(signatureSecretFile);
        int c = reader.read();
        while (c > -1) {
          secret.append((char) c);
          c = reader.read();
        }
        reader.close();
{code}
If IOException is thrown out of reader.read(), reader would be left unclosed.
