When I'm executing an MapReduce example on my modified Hadoop MapReduce, sometimes the reduce task give me this error, and the example doesn't finish:
[code] 2012-04-10 11:32:38,110 INFO hdfs.DFSClient.closeInternal:3231 Could not complete file /user/output//part-r-00000 retrying.... [/code] This happens normally, when I'm executing an example after restarting JT and TT, without restarting the Namenode and the datanode. What this error means? Please notice that this happens only to my modified version and not the official. I modified the version 0.20.1. -- Best regards,
