hi, Ryan
i'm trying to recover from disk full error on the namenode as well. i can fire
up namenode after printf \xff\xff\xff\xee\xff /var/name/current/edits
but now it's stuck in safe mode verifying blocks for hours... is there a way to
check progress on that?
or is there a way to speed that
Hey guys,
Really trying to get our namenode back up and running after a full disk
error last night. I've freed up a lot of space, however the NameNode still
fails to startup:

Could you backup your edits file, try $ printf \xff\xff\xff\xee\xff
edits, and start HDFS? It should work. - Andy
