Subject [jira] Commented: (HADOOP-3241) DFSFileInfo should also have field to say if the file is underconstrction
Date Mon, 14 Apr 2008 20:57:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12588791#action_12588791
] 

dhruba borthakur commented on HADOOP-3241:
------------------------------------------

If my memory serves me right, the "append" design says that if a Reader retrieves a list of
blocks from the namenode and the inode is marked "underConstruction", then the Reader can
do something more intelligent then returning failure when the application tries to read from
beyond the last known file size. This is more of an optimization and is not really required.

> It would be good to have a flag which says if the DFSFileInfo object corresponds to a
file under construction or not.
