IIUC you can move the data block files from one disk to another until they are evenly distributed. Give it a shot.
Just like that? Using "mv" command?I.e. move /data2/hdfs/data/current/subdir44/* to /data3/hdfs/data/current/subdir44/
?It's not atomic, so at some point, /data3/ would contain a file which is not a full copy of the same file on /data2/; later, both /data2 and /data3 would contain identical file.
