      Description

      Hi,

      The following code snippets throw an incompatible issue when I try to rolling update Hadoop Common from 2.7.7 to 3.X. The Hadoop-hdfs version is 2.7.1.

      @Test
      public void Test(){
      	RetryPolicy retryPolicy =
                  RetryUtils.getDefaultRetryPolicy(
                  		conf,
                          DFSConfigKeys.DFS_HTTP_CLIENT_RETRY_POLICY_ENABLED_KEY,
                          DFSConfigKeys.DFS_HTTP_CLIENT_RETRY_POLICY_ENABLED_DEFAULT,
                          DFSConfigKeys.DFS_HTTP_CLIENT_RETRY_POLICY_SPEC_KEY,
                          DFSConfigKeys.DFS_HTTP_CLIENT_RETRY_POLICY_SPEC_DEFAULT,
                          SafeModeException.class);
      }
      

      It throws an error: incompatible types: java.lang.Class<org.apache.hadoop.hdfs.server.namenode.SafeModeException> cannot be converted to java.lang.String

      Thanks a lot.
