RE: import errors with Eclipse Scala

Hi Ted, How can I import the relevant Spark projects into Eclipse? Do I need to add anything the Java Build Path in the project properties? Also, I have installed sbt on my machine. Is there a corresponding sbt command to the maven command below? Stefan Panayotov, PhD Home: 610-355-0919

RE: import errors with Eclipse Scala

Thanks, Jem. I added scala-compiler.jar from C:\Eclipse\eclipse\plugins\org.scala-ide.scala210.jars_4.1.0.201505250838\target\jars And looks like this resolved the issue. Thanks once again. Stefan Panayotov, PhD Home: 610-355-0919 Cell: 610-517-5586 email: spanayo...@msn.com spanayo

adding rows to a DataFrame

achieve this in Spark without doing DF.collect(), which will get everything to the driver and for a big data set I'll get OOM? BTW, I know how to use withColumn() to add new columns to the DataFrame. I need to also add new rows. Any help will be appreciated. Thanks, Stefan Panayotov, PhD

Python UDFs

ray[Double] = Array(a,b) val dv = new DenseVector(data) dv }) How can I write the corresponding function in Pyhton/Pyspark? Thanks for your help Stefan Panayotov, PhD Home: 610-355-0919 Cell: 610-517-5586 email: spanayo...@msn.com spanayo...@outlook.com spanayo...@comcast.net

RE: Python UDFs

Thanks, Jacob. But it seems that Python requires the RETURN Type to be specified. And DenseVector is not a valid return type, or I do not know the correct type to put in. Shall I try ArrayType? Any ideas? Stefan Panayotov, PhD Home: 610-355-0919 Cell: 610-517-5586 email: spanayo
