Subject [jira] [Commented] (HDFS-4158) FSDirectory#hasSnapshot will NPE when deleting an empty directory
Date Wed, 07 Nov 2012 01:18:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4158?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13492026#comment-13492026

Aaron T. Myers commented on HDFS-4158:
--------------------------------------

Ah, so you did. It might be better to use INodeDirectory#getChildrenList instead of INodeDirectory#getChildren
and then do a null check. Very minor issue though.

> The method attempts to iterate over the child list of the directory, but that list may
be null and this isn't handled currently.
