takeSample triggers 2 jobs

[Rares Vernica]

Hello,

I am using takeSample from the Scala Spark 1.2.1 shell:

scala> sc.textFile("README.md").takeSample(false, 3)


and I notice that two jobs are generated on the Spark Jobs page:

Job Id Description
1 takeSample at <console>:13
0  takeSample at <console>:13


Any ideas why the two jobs are needed?

Thanks!
Rares
