Wenchen Fan commented on SPARK-8608:
------------------------------------
How to reproduce this issue? I tried
{{{
val df = testData.select(rand())
println(df.showString(5))
println(df.showString(5))
println(df.collect().take(5).mkString("\n"))
}}}
but they return same result.
> After initializing a DataFrame with random columns and a seed, df.show should
> return same value
