Christian Kunz updated HADOOP-4103:
-----------------------------------
Description:
A whole bunch of datanodes became dead because of some network problems
resulting in heartbeat timeouts although datanodes were fine.
Many processes started to fail because of the corrupted filesystem.
In order to catch and diagnose such problems faster the namenode should detect
the corruption automatically and provide a way to alert operations. At the
minimum it should show the fact of corruption on the GUI.
