          Description

          When NN maintenance is performed on a large cluster, jobs end up failing. This is particularly bad for long running jobs. The client retry policy could be made configurable so that jobs don't need to be restarted.

            h3504_20120607.patch: adds a new conf property dfs.client.retry.max for DFSClient RPC retry policy as follows:

            • If dfs.client.retry.max == 0, use TRY_ONCE_THEN_FAIL.
            • If dfs.client.retry.max > 0, then
              1. use exponentialBackoff for
                • SafeModeException, or
                • IOException other than RemoteException; and
              2. use TRY_ONCE_THEN_FAIL for
                • non-SafeMode RemoteException, or
                • non-IOException.

            Need to add some tests.

            • Not sure if exponential backoff is flexible enough. Typically one wants to retry every 10 sec till about a minute and then retry every 60 sec.
            • You forgot about the connection retry.
            • Why is MiniDfsCluster changes needed?

            > Not sure if exponential backoff is flexible enough. Typically one wants to retry every 10 sec till about a minute and then retry every 60 sec.

            For exponential backoff, provided that the exponentialBackoff retry policy is used and the average sleep time of the first retry is 1 second, we have the following.

            n-th retry average sleep time (seconds) on average, the n-th retry will happen in (seconds)
            1 1 1
            2 2 3
            3 4 7
            4 8 15
            5 16 31
            ...
            n 2^(n-1) 2^n - 1

            The value of dfs.client.retry.max should depend on the failover time. Suppose the failover time is around 10 minutes. Then setting dfs.client.retry.max=10 will take ~17 minutes to finish all 10 reties. However, the last few retries will sleep for a long time. I think it is undesirable. Let me think about this more.

            > You forgot about the connection retry.

            Sure, will also change it.

            > Why is MiniDfsCluster changes needed?

            I just have moved the LOG message "Cluster is active" to waitActive(). I believe it is a better place for it.

            The javadoc warning is due to HADOOP-8491.

            TestFileLengthOnClusterRestart is due to HDFS-3522; filed HDFS-3525.
