> In branch HDFS-1312, there are many places use {{ObjectMapper}} instances to
> do the json-object transform. But {{ObjectMapper}} instance is relatively
> heavy, we should reuse them as possible. And In addition, {{ObjectMapper}} is
> thread safe, can see this link:http://wiki.fasterxml.com/JacksonFAQ.
> Here are related issues: HDFS-9724, HDFS-9768. We can see detail info in this
> issues.
