Yiqun Lin updated HDFS-11233:
-----------------------------
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.
