Subject [jira] [Commented] (HDFS-6245) datanode fails to start with a bad disk even when failed volumes is set
Date Mon, 21 Apr 2014 00:19:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13975324#comment-13975324

Arpit Agarwal commented on HDFS-6245:
-------------------------------------

It is hard to simulate this IOError from getCanonicalPath using unit tests. The other option
is mock based tests but that would be convoluted and probably require some refactoring.
