Stephan Ewen closed FLINK-1959. ------------------------------- > Accumulators BROKEN after Partitioning > -------------------------------------- > > Key: FLINK-1959 > URL: https://issues.apache.org/jira/browse/FLINK-1959 > Project: Flink > Issue Type: Bug > Components: Examples > Affects Versions: master > Reporter: mustafa elbehery > Assignee: Stephan Ewen > Priority: Critical > Fix For: 0.9 > > > while running the Accumulator example in > https://github.com/Elbehery/flink/blob/master/flink-examples/flink-java-examples/src/main/java/org/apache/flink/examples/java/relational/EmptyFieldsCountAccumulator.java, > > I tried to alter the data flow with "PartitionByHash" function before > applying "Filter", and the resulted accumulator was NULL. > By Debugging, I could see the accumulator in the RunTime Map. However, by > retrieving the accumulator from the JobExecutionResult object, it was NULL. > The line caused the problem is "file.partitionByHash(1).filter(new > EmptyFieldFilter())" instead of "file.filter(new EmptyFieldFilter())" -- This message was sent by Atlassian JIRA (v6.3.4#6332)
