> 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.
