Radim Kolar created HADOOP-8619: ----------------------------------- Summary: WritableComparator must implement no-arg constructor Key: HADOOP-8619 URL: https://issues.apache.org/jira/browse/HADOOP-8619 Project: Hadoop Common Issue Type: Improvement Components: io Affects Versions: 3.0.0 Reporter: Radim Kolar Fix For: 3.0.0, 2.0.0-alpha, 0.23.0 Attachments: writable-comparator.txt
Because of reasons listed here: http://findbugs.sourceforge.net/bugDescriptions.html#SE_COMPARATOR_SHOULD_BE_SERIALIZABLE comparators should be serializable. To make deserialization work, it is required that all superclasses have no-arg constructor. http://findbugs.sourceforge.net/bugDescriptions.html#SE_NO_SUITABLE_CONSTRUCTOR Simply add no=arg constructor to WritableComparator. -- This message is automatically generated by JIRA.
