URL: http://issues.apache.org/jira/browse/HADOOP-108
Project: Hadoop
Type: Bug

This morning - after upgrade of the system - something got wrong and we started
to get lot of exceptions.
Situation didn't change after removing everything and creating new file system.
Multiple exceptions on all data nodes:
