Subject [jira] Updated: (HADOOP-69) Unchecked lookup value causes NPE in FSNamesystemgetDatanodeHints
Date Wed, 08 Mar 2006 00:55:54 GMT
     [ http://issues.apache.org/jira/browse/HADOOP-69?page=all ]

Bryan Pendleton updated HADOOP-69:
----------------------------------

    Attachment: patch.txt

Check for null value after looking up blocks (ie, no known node has the block). Should prevent
the NPE. The correct value (no hints for unfound blocks) is returned.
