CodingCat dc9654638f SPARK-1240: handle the case of empty RDD when takeSample ... https://spark-project.atlassian.net/browse/SPARK-1240 It seems that the current implementation does not handle the empty RDD case when run takeSample In this patch, before calling sample() inside takeSample API, I add a checker for this case and returns an empty Array when it's a empty RDD; also in sample(), I add a checker for the invalid fraction value In the test case, I also add several lines for this case Author: CodingCat <zhunansjtu@gmail.com> Closes #135 from CodingCat/SPARK-1240 and squashes the following commits: fef57d4 [CodingCat] fix the same problem in PySpark 36db06b [CodingCat] create new test cases for takeSample from an empty red 810948d [CodingCat] further fix a40e8fb [CodingCat] replace if with require ad483fd [CodingCat] handle the case with empty RDD when take sample		2014-03-16 22:14:59 -07:00
