More information from the NameNode log. I don't understand... it is saying
that I cannot delete the corrupted file until the NameNode leaves safe mode,
but it won't leave safe mode until the file system is no longer corrupt. How
do I get there from here?
Thanks

Subject: Need help: fsck FAILs, refuses to clean up corrupt fs
I have a file system with some missing/corrupt blocks. However, running hdfs
fsck -delete also fails with errors. How do I get around this?
Thanks
John
