Patrick Wendell resolved SPARK-2861. ------------------------------------ Resolution: Fixed Fix Version/s: 1.1.0 Issue resolved by pull request 1786 [https://github.com/apache/spark/pull/1786] > Doc comment of DoubleRDDFunctions.histogram is incorrect > -------------------------------------------------------- > > Key: SPARK-2861 > URL: https://issues.apache.org/jira/browse/SPARK-2861 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 0.9.0, 0.9.1, 1.0.0 > Reporter: Chandan Kumar > Priority: Trivial > Fix For: 1.1.0 > > > The documentation comment of histogram method of DoubleRDDFunctions class in > source file DoubleRDDFunctions.scala is inconsistent. This might confuse > somebody reading the documentation. > Comment in question: > {code} > /** > * Compute a histogram using the provided buckets. The buckets are all open > * to the left except for the last which is closed > * e.g. for the array > * [1, 10, 20, 50] the buckets are [1, 10) [10, 20) [20, 50] > * e.g 1<=x<10 , 10<=x<20, 20<=x<50 > * And on the input of 1 and 50 we would have a histogram of 1, 0, 0 > {code} > The buckets are all open to the right (NOT left) except for the last which is > closed > For the example quoted, the last bucket should be 20<=x<=50. > Also, the histogram result on input of 1 and 50 would be 1, 0, 1 (NOT 1, 0, > 0). This works correctly in Spark but the doc comment is incorrect. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
