Problem with converting Spark Dataframe to H2OFrame

[ni...@cloudera.com]

Hi,

Get an exception while converting a Spark Dataframe to H2OFrame using either of the approaches below:

// Converting Spark dataframe - pcaData to H2O dataframe
import h2oContext.implicits._
val h2oFrame: H2OFrame = pcaData

or

val h2oFrame = h2oContext.asH2OFrame(pcaData)

The error that I see is:

I am using Spark version 1.6.1, Sparkling Water version 1.6.4, Scala version 2.10.4 and h2o-scala version 3.6.0.12. Any suggestions or insights ?

Thanks,

Was able to fix this. It was a library version issue, changed the h2o-scala version to 3.8.2.6.
