             Summary: ReuseObjectMapper in Hadoop Common
                 Key: HADOOP-14901
                 URL: https://issues.apache.org/jira/browse/HADOOP-14901

            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru
            Priority: Minor


It is recommended to reuse ObjectMapper, if possible, for better performance. We can aslo use ObjectReader or ObjectWriter to replace the ObjectMapper in some places: they are straightforward and thread safe.
