Subject [jira] Commented: (HADOOP-3513) Improve NNThroughputBenchmark log messages.
Date Mon, 09 Jun 2008 18:25:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12603639#action_12603639

Konstantin Shvachko commented on HADOOP-3513:
---------------------------------------------

> Wouldn't it better to wait until the namenode leaves safemode rather than forcing it
out?

I you start the name-node with an existing image and all data-nodes are down, which is what
the benchmark does,
then there is no chance the name-node will leave safe-mode naturally. So I have to force it
out.
