Subject RE: Hadoop Master Node failed
Date Wed, 25 Oct 2006 16:33:05 GMT
Short answer: no.

We're planning to fix that at some point, and as a stopgap you could backup
the namenode state (fsimage, edits) every once in a while, limiting the
damage, but as for the data that's lost - your only hope is to try and
extract it somehow from the dead disk.
