Hi, NN was unable to process any request since it's cast more exceptions. and then the NN can't be started, because fseditlog reads a unknown opcode when NN is loading edits file.
Now, the dfs.name.dir directory below is: [yuc...@d1950 ~]$ ll /home/yuchao/hadoop/name/current/ total 4332 -rw-rw-r-- 1 yuchao yuchao 14289 Sep 23 16:13 edits -rw-rw-r-- 1 yuchao yuchao 1049088 Sep 23 17:08 edits.new -rw-rw-r-- 1 yuchao yuchao 2179387 Sep 23 15:13 fsimage -rw-rw-r-- 1 yuchao yuchao 2184070 Sep 23 21:36 fsimage.ckpt -rw-rw-r-- 1 yuchao yuchao 8 Sep 23 15:13 fstime -rw-rw-r-- 1 yuchao yuchao 100 Sep 23 15:13 VERSION and the fs.checkpoint.dir directory is: [yuc...@d1950 ~]$ ll fordim/tmp/dfs/namesecondary/current/ total 4288 -rw-rw-r-- 1 yuchao yuchao 14289 Sep 23 18:03 edits -rw-rw-r-- 1 yuchao yuchao 4 Sep 23 18:03 edits.new -rw-rw-r-- 1 yuchao yuchao 2179387 Sep 23 18:03 fsimage -rw-rw-r-- 1 yuchao yuchao 2178424 Sep 23 18:03 fsimage.ckpt
