Eli Collins updated HADOOP-8041:
--------------------------------
Description:
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.

time a client performs an operation, eg could be weeks after the failover. But
we should eg log a warning eg the client first does a failover.
