Hi I am trying to invoke Hive UDF using
dataframe.select(callUdf("percentile_approx",col("C1"),lit(0.25))) but it
does not compile however same call works in Spark scala console I dont
understand why. I am using Spark 1.5.2 maven source in my Java code. I have
also explicitly added maven dependency hive-exec-1.2.1.spark.jar where
percentile_approx is located but still does not compile code please check
attached code image. Please guide. Thanks in advance.
