Aaron T. Myers commented on HDFS-3175:
--------------------------------------

Take a look at the end of [this comment|https://issues.apache.org/jira/browse/HDFS-1594?focusedCommentId=13020373&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13020373],
in which Eli articulates the reasoning why not to automatically leave safe mode upon having
enough disk space.

bq. The NameNodeResourceChecker only check whether the disk is available or not, whether the
system is automatically exit safemode or not is determined by NameNodeResourceMonitor.

You're right. My mistake.
