Felix Neutatz commented on FLINK-1392:
--------------------------------------
The second issue was fixed by your branch, but the standard example still fails:
{code:xml}
Exception in thread "main" org.apache.flink.compiler.CompilerException:
Error translating node 'Data Source "at main(ParquetProtobufOutput.java:69)
(org.apache.flink.api.java.io.CollectionInputFormat)" : NONE [[
GlobalProperties [partitioning=RANDOM] ]] [[ LocalProperties [ordering=null,
grouped=null, unique=null] ]]': This is supposed to be overridden by subclasses.
