    [ https://issues.apache.org/jira/browse/HDFS-3817?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13439133#comment-13439133

Suresh Srinivas commented on HDFS-3817:

+1 for the trivial patch. No tests are needed as HADOOP-8711 adds test for this functionality.

> When NN is in safemode, any namespace change request could cause a SafeModeException
to be thrown and logged in the server log, which can make the server side log grow very quickly.

> The server side log can be more concise if only the exception and error message will
be printed but not the stack trace.
