    Description

      We see a lot of warning messages on each data-node during startup and upgrading from 0.17 to 0.18 saying:

      2008-07-08 22:22:15,711 WARN org.apache.hadoop.dfs.DataNode: Block /grid/3/hadoop/var/hdfs/data/current/blk_3359714082706415785 does not have a metafile!
      

      The message received twice for each block, because the block information is first read buy the data-node itself and then by the block scanner.
