Hi - When you get an exception stack trace like this ..
Caused by: org.apache.flink.client.program.OptimizerPlanEnvironment$ProgramAbortException at org.apache.flink.streaming.api.environment.StreamPlanEnvironment.execute(StreamPlanEnvironment.java:66) at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.java:1507) at org.apache.flink.streaming.api.scala.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.scala:654) what is the recommended approach of debugging ? I mean what kind of errors can potentially lead to such a stacktrace ? In my case it starts from env.execute(..) but does not give any information as to what can go wrong. Any help will be appreciated. regards. -- Debasish Ghosh http://manning.com/ghosh2 http://manning.com/ghosh Twttr: @debasishg Blog: http://debasishg.blogspot.com Code: http://github.com/debasishg
