get specific row from spark dataframe

Question

Is there any alternative for df[100, c(\"column\")] in scala spark data frames. I want to select specific row from a column of spark data frame. for example

Answer 1

This is how I achieved the same in Scala. I am not sure if it is more efficient than the valid answer, but it requires less coding

val parquetFileDF = sqlContext.read.parquet("myParquetFule.parquet")

val myRow7th = parquetFileDF.rdd.take(7).last
