Subject RE: Namenode crashes while rolling edit log from secondary namenode

Eli,

Thanks for responding to my question. I guess what you're mentioning are
dfs.name.edits.dir and dfs.namenode.name.dir. They do not contain any
NFS mounted directories. They were all accessible (can be seen by UNIX
shell commands such as ls and du) when the namenode went down. The error
message is just the symptom. It is not the cause of the failure.

Hey Zhang,

Are the directories specified by dfs.namenode.[name|edits].dir
accessible? Perhaps they're NFS mounts that are flaking out?

Thanks,
Eli
