Subject problem with upgrading from HDFS 0.21 to HDFS 1.0.4
Date Tue, 20 Nov 2012 23:57:48 GMT
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?
