Subject [jira] [Updated] (HDFS-2952) HA: NN should not start with upgrade option or with a pending an unfinalized upgrade
Date Fri, 17 Feb 2012 22:28:57 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2952?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aaron T. Myers updated HDFS-2952:
---------------------------------

    Attachment: HDFS-2952-HDFS-1623.patch

Here's a little patch which addresses the issue. An HA NN already refused to start if a previous
upgrade was in progress, but this patch adds a test for the behavior.

I also took the liberty of fixing 3 little typos I noticed while preparing this patch.

> For simplicity, we should require that upgrades be done with HA disabled. We might support
this in future versions.
