IOException: cannot find BPOfferService for bpid

New Contributor

I'm getting these errors while running a mapreduce job against Cloudera and the datanode appears to have gone down. Any ideas why?

Re: IOException: cannot find BPOfferService for bpid

Master Guru
The reason for a DN having gone down would be in its own logs, typically as a FATAL log level entry near the exit period. If there's no such log and the exit seems abrupt, then checkout its stdout and stderr files.
