Date Fri, 20 Jul 2012 22:49:35 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3643?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andy Isaacson updated HDFS-3643:
--------------------------------

    Attachment: hdfs3643.txt

Attaching simple patch to avoid walking off the end of the string, and to do something sane
when the return value is incorrectly specified.

> This loop needs to check for {{'\0'}}. Also the following {{if/else if/else if}} cascade
doesn't handle unexpected values.
