Subject [jira] [Commented] (HDFS-4138) BackupNode startup fails due to uninitialized edit log
Date Mon, 05 Nov 2012 15:24:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13490684#comment-13490684

Kihwal Lee commented on HDFS-4138:
----------------------------------

According to HDFS-4114, it looks like BackupNode is not going away any time soon.  I am attaching
a minimal patch to get rid of the exception from metrics initialization.  For branch-2, we
also need HDFS-3625.

> It was notices by TestBackupNode.testCheckpointNode failure. When a backup node is getting
started, it tries to enter active state and start common services. But when it fails to start
services and exits, which is caught by the exit util.
