WritableShimSerialization介绍

[英]A serializer that understands how to write objects that implement WritableShim out to a Hadoop stream. This class must be present in the io.serializations key of a Hadoop config for the Hadoop runtime to find and instantiate it.
[中]了解如何将实现WritableShim的对象写入Hadoop流的序列化程序。这门课必须出现在io中。序列化Hadoop配置的键，以便Hadoop运行时查找并实例化它。
