> On occasion I get an IOE trying to close a MapFile I've just opened and filled.  Below
is the content of the namenode log.  The first thing in it after startup messages is the IOE
followed by other messages about '...current leaseholder is trying to recreate file'.  It
repeats for ever.  This is TRUNK r567876.
> I filed this issue at Raghu's suggestion.  Here's what he said on the list:
> .bq Yes, the earler message was also from Namenode log. Before that line there should
have been a message that adds a block to this file in the same log. I think you should file
a Jira for this. It probably related to HADOOP-999. Raghu.
