> Now in MapReduce, there are some places creating a new ObjectMapper instance every time.
In wiki of ObjectMapper, it suggested:
> {code}
> Further: it is beneficial to use just one instance (or small number of instances) for
data binding; many optimizations for reuse (of symbol tables, some buffers) depend on ObjectMapper
instances being reused. 
> {code}
> http://webcache.googleusercontent.com/search?q=cache:kybMTIJC6F4J:wiki.fasterxml.com/JacksonFAQ+&cd=4&hl=ja&ct=clnk&gl=jp,
it's similar to HDFS-9724.
