Description
Looking in log, I see:
2008-08-26 18:57:23,602 INFO org.apache.hadoop.dfs.DFSClient: org.apache.hadoop.ipc.RemoteException: java.io.IOException: File /hbase/aa0-000-8.u.powerset.com/log_208.76.45.95_1218666613846_60020/hlog.dat.1219776799293 could only be replicated to 0 nodes, instead of 1

... and then:

... and so on.
Meantime clients are trying to do updates and getting below:

..
DFSClient seems horked.
Need to be able to ride out these kind of event.
Restart is needed.
Test this by filling HDFS.
