Description

We should update the deprecated APIs after Jackson upgraded. This issue is similar to HDFS-11233. In MAPREDUCE, there is just one place using deprecated API. We can updated the code here.

class JobSubmitter {
  protected static final Log LOG = LogFactory.getLog(JobSubmitter.class);
  private static final ObjectReader READER =
      new ObjectMapper().reader(Map.class);
