[3/3] flink git commit: [FLINK-4316] [core] [hadoop compatibility]
Make flink-core independent of Hadoop
Posted by se...@apache.org.
[FLINK-4316] [core] [hadoop compatibility] Make flink-core independent of Hadoop
This commit moves all 'Writable' related code to the 'flink-hadoop-compatibility' project
and uses reflection in 'flink-core' to instantiate WritableTypeInfo when needed.
This closes #2338
