> Ran into this confusing message on our local HA setup.
> One of the namenode was down and the other was in standby mode.
> The namenode was not able to come out of safe mode so we did transitionToActive with
forceActive switch enabled.
> Due to change in HDFS-2949,  it will try connecting to all the  namenode  to see whether
they are active or not.
> But since the other namenode is down it will try connect to that namenode for 'ipc.client.connect.max.retries'
number of times.
> Every time it is not able to connect, it will log a message :
> INFO ipc.Client: Retrying connect to server: <server name>. Already tried 0 time(s);
retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=50, sleepTime=1000 MILLISECONDS)
> Since in our configuration, the number of retries is 50, it will show this message 50
times.
