Subject [jira] [Commented] (HDFS-2704) NameNodeResouceChecker#checkAvailableResources should check for inodes
Date Fri, 13 Apr 2012 14:06:24 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2704?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13253392#comment-13253392

Robert Joseph Evans commented on HDFS-2704:
-------------------------------------------

I personally would like to see it go into safemode, just because you never know what in the
system will start to have problems when you run out of inodes, or any other resource for that
matter.  I would hope most standard things would fail gracefully, but you never know and having
a corrupted edit log because we tried to roll them when there were no inodes available is
a very bad thing.

However inodes are also a file system resource that needs to be available (you can run out
of inodes but have free space).
