Subject [jira] [Commented] (HDFS-3385) ClassCastException when trying to append a file
Date Fri, 11 May 2012 00:35:48 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3385?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13272946#comment-13272946
] 

Hudson commented on HDFS-3385:
------------------------------

Integrated in Hadoop-Hdfs-trunk-Commit #2301 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk-Commit/2301/])
    HDFS-3385. The last block of INodeFileUnderConstruction is not necessarily a BlockInfoUnderConstruction,
so do not cast it in FSNamesystem.recoverLeaseInternal(..). (Revision 1336976)

     Result = SUCCESS
