[jira] [Updated] (SPARK-2251) MLLib Naive Bayes Example
SparkException: Can only zip RDDs with same number of elements in each
partition
[ https://issues.apache.org/jira/browse/SPARK-2251?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Reynold Xin updated SPARK-2251:
-------------------------------
Description:
I follow the exact code from Naive Bayes Example (http://spark.apache.org/docs/latest/mllib-naive-bayes.html) of MLLib.
When I executed the final command:
val accuracy = 1.0 * predictionAndLabel.filter(x => x._1 == x._2).count() / test.count()
It complains "Can only zip RDDs with same number of elements in each partition".
I got the following exception:
