Hi all, I'm used to work with the version 0.20.203 but now I'm trying to update to the most recent version of MR1 that if I'm not wrong I think that it is the 1.2.1.
With the same configuration and same script (I'm using the mapred-examples) it seems that it works, also the output is exactly with both versions. However while I was reviewing the logs I have found some warnings and errors. These errors are related with the message "jobtracker.info could only be replicated to 0 nodes, instead of 1" which I have been searching over the net and it could be produced by many reasons. After these errors it seems that the other things works right. Except the last messages "java: no process found" that I don't know why appears. - Can someone help me to find the origin of these errors? - Can someone check that all the process (and the result) is OK in spite of these errors? I adjunct here my log to provide help. Thanks for all!! =)
