Ben Humphrey created ZEPPELIN-308:
-------------------------------------
Summary: Unable to create more than 22 parameters for a case class
Key: ZEPPELIN-308
URL: https://issues.apache.org/jira/browse/ZEPPELIN-308
Project: Zeppelin
Issue Type: Bug
Components: Core
Environment: Azure HDInsight Spark Preview
Reporter: Ben Humphrey
I am using Zeppelin in Azure's HDInsight and am unable to have more than 22
columns when I create a "case class" definition. Apparently this was fixed in
2.11 of Scala and was wondering which version is Zeppelin using for Scala? Is
there a plan on when Zeppelin will have 2.11 perhaps?
As an example, if you paste this into a Zeppelin notebook (at least in
HDInsight) it won't print the messages and will fail:
println("Start of application")
case class OrderDetail(AAA: String, BBB: String, CCC: String, EEE: String, FFF:
String, GGG: String, HHH: String, III: String, JJJ: String, KKK: String, LLL:
String, MMM: String, NNN: String, OOO: String, PPP: String, QQQ: String, RRR:
String, SSS: String, TTT: String, UUU: String, VVV: String, WWW: String,
BrokenIfHere: String)
println("Doesn't get here if 23+ columns exist")
But if you remove the last parameter (BrokenIfHere) it will work. Here is the
Scala Jira issue for reference:
https://issues.scala-lang.org/browse/SI-7296
This apparently was fixed around 2 years ago in Scala.
Thanks so much.
