             Summary: ABFS: Implement ThreadLocal for ObjectMapper in AzureHttpOperation via config option with static shared instance as an alternative.
                 Key: HADOOP-19149
                 URL: https://issues.apache.org/jira/browse/HADOOP-19149
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/azure
    Affects Versions: 3.4.0
            Reporter: Mukund Thakur
            Assignee: Mukund Thakur


While doing internal tests on Hive TPCDS queries we have seen many instances of ObjectMapper have been created in an Application Master thus sharing a thread local object mapper instances will improve the performance.
