> Currently we always warn for each client operation made to a NN we've
> failedover to:
> {noformat}
> hadoop-0.24.0-SNAPSHOT $ ./bin/hdfs dfs -lsr /
> 12/02/08 17:43:04 WARN retry.RetryInvocationHandler: Exception while invoking
> getFileInfo of class
> org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB after 0
> fail over attempts. Trying to fail over immediately.
> {noformat}
> I'm going to remove this warning in HDFS-2922 since we shouldn't warn every
> time a client performs an operation, eg could be weeks after the failover.
> But we should eg log a warning when the client first does a failover so it
> shows up eg in the MR and HBase logs.
