spark dataset.cache is not thread safe

[Amit Sharma]

Hi , I wrote a code in future block which read data from dataset and cache
it which is used later in the code. I faced a issue that data.cached() data
will be replaced by concurrent running thread . Is there any way we can
avoid this condition.

val dailyData = callDetailsDS.collect.toList
val adjustedData = dailyData.map(callDataPerDay => Future{



  val data = callDetailsDS.filter((callDetailsDS(DateColumn) geq (some
conditional date ))
    data.cache()
