Dear Hadooper,
Has anyone tried HDFS RAID? I am trying Hadoop 0.22.0.
I got an error at
"at org.apache.hadoop.raid.BlockFixer.getDFS(BlockFixer.java:375)"
which said that
" org.apache.hadoop.hdfs.DistributedRaidFileSystem cannot be cast to
org.apache.hadoop.hdfs.DistributedFileSystem"
but don't how to fix it.
I have found that DistributedRaidFileSystem extended "FilterFileSystem"
which is not inherited from "DistributedFileSystem".
I want to know whether this is a bug in BlockFixer.
or just because I have make a wrong configuration?
Thanks for reading.
