what does it mean -- java.io.IOException: Filesystem closed

Hi , Running jadoop job from time to time I got such exception (from one of the reducers): The questions are : 1) What does this exception means for the data integrity? 2) Does it mean that part of the data which reducer responsible for (and got exception) are lost? 3) What could cause for such

Hi Oleg, I had the same exception here for both hadoop-0.21.0 and 0.21.0 It looks it is still an open bug in hadoop: https://issues.apache.org/jira/browse/MAPREDUCE-2060, https://issues.apache.org/jira/browse/HDFS-925. I also want to know how to fix it. On 11/2/10 11:38 AM, Oleg
