Hi there,
not sure if its a bug of 0.9-SNAPSHOT version, or me just doing something wrong. I have this simple scala program: val input = env.readTextFile("hdfs://my.host.com:54310/home/sampleRaw") And I get the following error: org.apache.flink.client.program.ProgramInvocationException: The program execution failed: java.lang.Exception: The data preparation for task 'Reduce (SUM(2))' , caused an error: Error obtaining the sorted input: Thread 'SortMerger spilling thread' terminated due to an exception: The user-defined combiner failed in its 'open()' method.

Any help would be really appreciated! Thank you! |
Hi, you are doing everything correct. This is a bug in the Flink runtime. I created a JIRA (https://issues.apache.org/jira/browse/FLINK-1574) and will push a fix later this evening once all tests have passed. Thanks for reporting the issue!
