Regarding your latest error:
java.io.IOException: Incompatible clusterIDs in /mnt/disk1/hadoop/hdfs/data: namenode clusterID = CID-297a140f-7cd6-4c73-afc8-bd0a7d01c0ee; datanode clusterID = CID-7591e6bd-ce9b-4b14-910c-c9603892a0f1 at
Looks like your VERSION file has different cluster IDs present in NameNode and DataNode that need to be correct. So please check.
cat <dfs.namenode.name.dir>/current/VERSION cat <dfs.datanode.data.dir>/current/VERSION
Hence Copy the clusterID from nematode and put it in the VERSION file of datanode and then try again.
