[jira] [Created] (HADOOP-15698) KMS startup logs don't show

Kitti Nanasi created HADOOP-15698:
-------------------------------------

             Summary: KMS startup logs don't show
                 Key: HADOOP-15698
                 URL: https://issues.apache.org/jira/browse/HADOOP-15698
             Project: Hadoop Common
          Issue Type: Bug
          Components: kms
    Affects Versions: 3.1.0
            Reporter: Kitti Nanasi
            Assignee: Kitti Nanasi


During KMs startup, log4j logs don't show up resulting in important logs getting omitted. This happens because log4 initialisation only happens in KMSWebApp#contextInitialized and logs written before that don't show up.

For example the following log never shows up:

[https://github.com/apache/hadoop/blob/a55d6bba71c81c1c4e9d8cd11f55c78f10a548b0/hadoop-common-project/hadoop-auth/src/main/java/org/apache/hadoop/security/authentication/util/ZKSignerSecretProvider.java#L197-L199]

Another example is that the KMS startup message never shows up in the kms logs.

Note that this works in the unit tests, because MiniKMS sets the log4j system property.
