问题 I have to visualiase some map thingy in Zeppelin via spark and JS (angular interpreter in this case). Zeppelin has this binding feature but it gives a little knowledge about usage. I would like to click on the button, evaluate some stuff, than send the id_selected_arr to the spark via binding. In %angular window <input type="button" value="Click me" ng-click="eval()" ng-model="id_selected_arr"/> In %spark2 window var result = z.angular("id_selected_arr") I get: result: Object = id_selected

Furthermore I would like to be able to access my s3 buckets. I followed this guide and this other one however I can not seem to run scala code from zeppelin to my cluster.

问题 In this question I was told how to print a dataframe using zeppelin's z.show command. This works well except for 'WrappedArray' appearing in the lemma column: I have tried this: z.show(dfLemma.select(concat_ws(",", $"lemma"))) but it just gave me a list of words, not nicely formatted and I also want the racist column in my output. Any help is much appreciated. 回答1: Here's a suggestion for formatting your array column: import org.apache.spark.sql.Column import org.apache.spark.sql.functions._

问题 I have a script running in a paragraph with the Spark interpreter in Zeppelin. It has an import and the name imported can be resolved from the global namespace and also from a function, but not from a method inside a class. This runs well on my computer's installation of Scala (2.12) but it doesn't work in Zeppelin (Scala 2.11). import java.util.Calendar def myFun: String = { // this works return Calendar.getInstance.toString } class MyClass { def myFun(): String = { // this doesn't return
