Akira Ajisaka commented on HDFS-11233:
--------------------------------------

+1. I ran the failed tests and all of them without TestTrashWithSecureEncryptionZones and
TestTrashWithSecureEncryptionZones are succeeded. The two failures are related to HADOOP-13890.

> 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.
