The default extension value DFS_NAMENODE_SAFEMODE_EXTENSION_DEFAULT not used here, it just
use 0.

Sorry I didn't notice your comment in this JIRA before I fixed this today. See [HDFS-11095].

> I tried starting a NameNode on a freshly formatted cluster, and it produced this WARN
log:
> {noformat}
> 16/11/01 16:42:44 WARN blockmanagement.BlockManagerSafeMode: forceExit used when normal
exist would suffice. Treating force exit as normal safe mode exit.
> {noformat}
> I didn't do any special commands related to safemode, so this log should be quashed.
> I didn't try the branch-2's, but it's likely this issue exists there as well.
