      Description

      In HDFS-9724, it have reused the ObjectMapper instance to improve the performance in WebHDFS. But in other places, it still using ObjectMapper by new ObjectMapper(). We probably need a comprehensive review across the whole codebase to look for this pattern and modify them. In MAPREDUCE-6626, YARN-4668, these jiras also work for this.
