Ray commented on IGNITE-8697: ----------------------------- Hello [~samaitra], Thanks for the fix. I validated this fix by running my WordCount application in both standalone mode and cluster mode. The data can be inserted. But I found another problem here. The data written into Ignite is not correct. My application counts the word occurrence in this the following sentence. "To be, or not to be,--that is the question:--", "Whether 'tis nobler in the mind to suffer", "The slings and arrows of outrageous fortune", "Or to take arms against a sea of troubles, The count of word "to" should be 9. But when I check the result in Ignite, all the values of every word is 1. Clearly it's wrong. The reproducer program is the same as I attached above. Please let me know if you can reproduce this issue. > Flink sink throws java.lang.IllegalArgumentException when running in flink > cluster mode. > ---------------------------------------------------------------------------------------- > > Key: IGNITE-8697 > URL: https://issues.apache.org/jira/browse/IGNITE-8697 > Project: Ignite > Issue Type: Bug > Affects Versions: 2.3, 2.4, 2.5 > Reporter: Ray > Priority: Blocker > > if I submit the Application to the Flink Cluster using Ignite flink sink I > get this error > > java.lang.ExceptionInInitializerError > at > org.apache.ignite.sink.flink.IgniteSink$SinkContext.getStreamer(IgniteSink.java:201) > at > org.apache.ignite.sink.flink.IgniteSink$SinkContext.access$100(IgniteSink.java:175) > at org.apache.ignite.sink.flink.IgniteSink.invoke(IgniteSink.java:165) > at > org.apache.flink.streaming.api.functions.sink.SinkFunction.invoke(SinkFunction.java:52) > at > org.apache.flink.streaming.api.operators.StreamSink.processElement(StreamSink.java:56) > at > org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.pushToOperator(OperatorChain.java:560) > at > org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.collect(OperatorChain.java:535) > at > org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.collect(OperatorChain.java:515) > at > org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:679) > at > org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:657) > at > org.apache.flink.streaming.api.operators.TimestampedCollector.collect(TimestampedCollector.java:51) > at > org.myorg.quickstart.InstrumentStreamer$Splitter.flatMap(InstrumentStreamer.java:97) > at > org.myorg.quickstart.InstrumentStreamer$Splitter.flatMap(InstrumentStreamer.java:1) > at > org.apache.flink.streaming.api.operators.StreamFlatMap.processElement(StreamFlatMap.java:50) > at > org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.pushToOperator(OperatorChain.java:560) > at > org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.collect(OperatorChain.java:535) > at > org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.collect(OperatorChain.java:515) > at > org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:679) > at > org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:657) > at > org.apache.flink.streaming.api.operators.StreamSourceContexts$NonTimestampContext.collect(StreamSourceContexts.java:104) > at > org.apache.flink.streaming.api.functions.source.SocketTextStreamFunction.run(SocketTextStreamFunction.java:110) > at > org.apache.flink.streaming.api.operators.StreamSource.run(StreamSource.java:87) > at > org.apache.flink.streaming.api.operators.StreamSource.run(StreamSource.java:56) > at > org.apache.flink.streaming.runtime.tasks.SourceStreamTask.run(SourceStreamTask.java:99) > at > org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:306) > at org.apache.flink.runtime.taskmanager.Task.run(Task.java:703) > at java.lang.Thread.run(Thread.java:748) > Caused by: java.lang.IllegalArgumentException: Ouch!
