--------------------------------
Summary: Use getTrimmedStrings when reading serialization keys
Key: HADOOP-11512
URL: https://issues.apache.org/jira/browse/HADOOP-11512
Project: Hadoop Common
Issue Type: Bug
Components: conf
Affects Versions: 2.6.0
Reporter: Harsh J
Priority: Minor
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.
