Subject [jira] [Commented] (HDFS-2914) HA: Standby should not enter safemode when resources are low
Date Mon, 13 Feb 2012 21:56:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2914?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13207256#comment-13207256
] 

Aaron T. Myers commented on HDFS-2914:
--------------------------------------

bq. I would rather leave this as is since I could easily make the problem happen with 10s
sleep.

I don't follow this. This seems to only serve to make the test take longer to run, without
providing much benefit. Am I missing something?

> When shared edits dir is bounced, standby NN is put into safemode by the NameNodeResourceMonitor().
However, there is no path for it to exit out of safe mode when shared edits dir reappears.
