zhubin created HADOOP-11133:
-------------------------------
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.
