Hi
I am experiencing a lot of tasks failures while running any Hadoop
application.
In particular, I get the following warnings:
Error initializing attempt_201106081500_0018_r_000000_0:
java.io.IOException: Could not obtain block: blk_-7386162385184325734_1214
file=/home/hadoop/data/mapred/system/job_201106081500_0018/job.xml
Looking in the forums, it seems it has something to do with /etc/hosts
settings, because I cannot also access the jobtracker web interface via the
hostname, but can access it via the actual IP address.
I set the /etc/hosts in all the VMs as per
<ip address> hostname
Any idea?
Thanks
