Class definition with more than 22 arguments Can you switch to 2.11 ? The following has been fixed in 2.11: https://issues.scala-lang.org/browse/SI-7296 Otherwise consider packaging related values into a case class of their own. On Tue, Sep 22, 2015 at 8:48 PM, satish chandra j <jsatishc

Re: Scala Limitation - Case Class definition with more than 22 arguments

You can implement your own case class supporting more then 22 fields. It is something like: class MyRecord(val val1: String, val val2: String, ... more then 22, in this case f.e. 26) extends Product with Serializable { def canEqual(that: Any): Boolean = that.isInstanceOf[MyRecord] def

Re: Scala Limitation - Case Class definition with more than 22 arguments

If you need to understand what is the magic Product then google up Algebraic Data Types and learn it together with what is Sum type. One option is http://www.stephanboyer.com/post/18/algebraic-data-types Enjoy, Petr On Wed, Sep 23, 2015 at 9:07 AM, Petr Novak wrote: > I'm

Re: Scala Limitation - Case Class definition with more than 22 arguments

HI Andy, So I believe if I opt pro grammatically building the schema approach, than it would not have have any restriction as such in "case Class not allowing more than 22 Arguments" As I need to define a schema of around 37 arguments Regards, Satish Chandra On Wed, Sep 23, 2015 at 9:50 AM,

Re: Scala Limitation - Case Class definition with more than 22 arguments

Yes and I would recommend it because it can be made generic and reusable too On Wed, Sep 23, 2015 at 5:37 PM, satish chandra j wrote: > HI Andy, > So I believe if I opt pro grammatically building the schema approach, than > it would not have have any restriction as

Scala Limitation - Case Class definition with more than 22 arguments

HI All, Do we have any alternative solutions in Scala to avoid limitation in defining a Case Class having more than 22 arguments We are using Scala version 2.10.2, currently I need to define a case class with 37 arguments but getting an error as "*error: Implementation restriction: case classes

Re: Scala Limitation - Case Class definition with more than 22 arguments

Alternatively, I would suggest you looking at programmatically building the schema refer to http://spark.apache.org/docs/latest/sql-programming-guide.html#programmatically-specifying-the-schema Cheers Andy On Wed, Sep 23, 2015 at 2:07 PM, Ted Yu wrote: > Can you switch to

Re: Scala Limitation - Case Class definition with more than 22 arguments

Can you switch to 2.11 ? The following has been fixed in 2.11: https://issues.scala-lang.org/browse/SI-7296 Otherwise consider packaging related values into a case class of their own. On Tue, Sep 22, 2015 at 8:48 PM, satish chandra j wrote: > HI All, > Do we have any
