Thanks for the response, I have several more questions: *1) you should run zinc incremental compiler* I run "./build/zinc-0.3.9/bin/zinc -scala-home $SCALA_HOME -nailed -start" but the compilation time of "build/mvn -DskipTests package' is still about 9 mins. Is this normal?
*2) if you want breakpoints that should likely be done in local mode* What do you mean by local mode? I've downloaded the latest version from github, and then made my changes on it. *3) adjust the log4j.properties settings and you can start to see the logInfo* I've copied log4j.properties from log4j.properties.template and is it set: log4j.rootCategory=INFO, console But I still do not see the logInfo in the console. -- View this message in context: http://apache-spark-developers-list.1001551.n3.nabble.com/what-is-the-best-way-to-debug-spark-mllib-tp15809p15815.html Sent from the Apache Spark Developers List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@spark.apache.org For additional commands, e-mail: dev-h...@spark.apache.org
