Subject [jira] [Created] (HADOOP-11512) Use getTrimmedStrings when reading serialization keys
Date Tue, 27 Jan 2015 14:07:37 GMT
Harsh J created HADOOP-11512:

             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.
