Hi
My NameNode is crashed. It gave a NullPointerException at
FsDirectory.addChild....
1) My Hadoop version 1.0.3
2) I patched a code for identifying the files throwing
NullPointerException - I found those files.
3) Now I want to remove those file operations in the edits file
4) I converted the edits file to edits.xml using Hadoop 2 tool - OEV
5) I removed the unwanted file ops and convered edit.xml to edits binary
format using same OEV tool of Hadoop 2
6) If I put this edits file, NameNode is throwing Unexpected version
IOException in FSNameSystem.java
How can I recover my NameNode? NameNode starts if I perform another
option of skiping the files that throws NullPointerException (later I was able
to build a new FsImage)
Is this approach correct? Is there is any good option?
Thanks and Regards
