Subject Re: Issue with loading dependencies and jars
Date Sat, 10 Mar 2018 01:42:36 GMT
Where does the classpath in spark-submit originate? Is compute-classpath.sh
not the source?

As noted previously, the stable-ordering fix by me in compute-classpath.sh
no longer seems to be effective either.

Looks like some tracing of classpath assembly through the Spark command
runner is required:
https://github.com/apache/predictionio/blob/develop/tools/src/main/scala/org/apache/predictionio/tools/Runner.scala#L185

Unless someone with more knowledge of these internals could weigh-in…
Donald? 😬😊
