java.io.IOException: All datanodes are bad. Aborting...
I have 2 directories listed for dfs.data.dir and one of them got to 100% used during a job I ran. I suspect thats the reason I see this error in the logs. Can someone please confirm this? thanks

Did you do the clean work on all the datanodes? rm -Rf /path/to/my/hadoop/dfs/data On 6/20/08, novice user [EMAIL PROTECTED] wrote: Hi Mori Bellamy, I did this twice. and still the same problem is persisting.
