> In the file
> {{hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/io/serializer/SerializationFactory.java}},
> we grab the IO_SERIALIZATIONS_KEY config as Configuration#getStrings(…)
> which does not trim the input. This could cause confusing user issues if
> someone manually overrides the key in the XML files/Configuration object
> without using the dynamic approach.
> The call should instead use Configuration#getTrimmedStrings(…), so the
> whitespace is trimmed before the class names are searched on the classpath.
