      Description

      After HADOOP-12705, the Jackson version upgraded from 2.2.3 to 2.7.8. This lead many APIs which we are used in hadoop being deprecated. Since 2.5, these two APIs are deprecated: ObjectReader#readerFor(Class<?> type),ObjectWriter#writerWithType(JavaType rootType)(http://fasterxml.github.io/jackson-databind/javadoc/2.6/com/fasterxml/jackson/databind/ObjectMapper.html).

      According to the doc of ObjectMapper, we can use ObjectReader#readerFor(Class<?> type) and ObjectWriter#writerFor(JavaType) instead.
