I'm writing a mapred app in Hadoop 0.16.4 in which I implement my own
inputsplit, called BioFileSplit, that extends FileSplit (it adds one int data
field to FileSplit). Testing my program in Eclipse yielded the exception trace
that roughly looks as follows:
Task Id : task_200807011030_0004_m_00

Hm, tried it (simply edited with vi, removed the last line). I did it with
both edits file and fsimage file (I see references to FSEditLog.java and
FSImage.java in the stack trace below), but that didn't seem to help. Namenode
just doesn't start at all. I can't see any errors in logs due to a
I remember dhruba telling me about this once.
Yes, Take a backup of the whole current directory.
As you have seen, remove the last line from edits and try to start the
NameNode.
If it starts, then run fsck to find out which file had the problem.
Thanks,
