-------------------------------

             Summary: failed to read correct content of keystore password file in hadoop-kms
                 Key: HADOOP-11133
                 URL: https://issues.apache.org/jira/browse/HADOOP-11133
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 3.0.0, 2.6.0
            Reporter: zhubin


When setup kms service to enable CFS feature, I created the keystore password file and input
the password content (like '123456'). But it failed to start kms service with below error:
java.io.IOException: Keystore was tampered with, or password was incorrect

As debugging, the failure was caused by the invalid password content due the code read more
char which is invisible (like file ending char). So the right behavior is to filter out the
invisible chars during reading password file.
