hi all, It seems it's not supported to upgrade hadoop from 0.21 to the stable version 1.0.4 . The 'linkBlocks' function in the 'DataStorage.java'(v1.0.4) can not work well , because the datanode storage structure of the former is different from the latter ,there are finalized and rbw directorys under $dfs.datanode.data.dir/current. Do you have some suggestions to deal with this problem?
