Is there any way to uncache RDD?

0 votes
I used cache() to cache the data in memory but I realized to see the performance without cached data I need to uncache it to remove data from memory:

rdd.cache();
//doing some computation
...
rdd.uncache()
but I got the error said:

value uncache is not a member of org.apache.spark.rdd.RDD[(Int, Array[Float])]

I don't know how to do the uncache then!
