-------------------------------
Summary: SerializationFactory shouldn't throw a
NullPointerException if the serializations list is empty
Key: HADOOP-8588
URL: https://issues.apache.org/jira/browse/HADOOP-8588
Project: Hadoop Common
Issue Type: Improvement
Components: io
Affects Versions: 2.0.0-alpha
Reporter: Harsh J
Priority: Minor
The SerializationFactory throws an NPE if
CommonConfigurationKeys.IO_SERIALIZATIONS_KEY is set to an empty list in the
config.
It should rather print a WARN log indicating the serializations list is empty,
and start up without any valid serialization classes.
