Error while generating dataset.

[张醒之]

Hello,

I'm trying to runBenchMark on a hadoop cluster running hadoop 2.7.3.

In the dataGenetation-run_query.log, it shows as follows:

Error: java.io.IOException: ################# ERROR  Task 1/80 ###########################

Message:HadoopClusterExec.DEBUG_EXCEPTION_MESSAGESStackTrace:

Is this a problem with the Hadoop cluster configuration, or JVM  configuration?

Thanks for the help in advance.

Hi,
please remove "-testDebugMessages" from your conf/userSettings.conf. This option will throw an exection ON PURPOSE instead of executing the data generation job. It is ment do debug settings and environment issues, but in this case it masks your actual problem (return/error code 143). I will anwer in your other thread https://groups.google.com/forum/#!topic/big-bench/hqoQbnEzWII shortly after this one.

Cheers Michael
