I just upgrade from Spark 1.6.1 to 2.0, and got an java compile error: *error: cannot access DeveloperApi* * class file for org.apache.spark.annotation.DeveloperApi not found*
>From the Spark 2.0 document ( https://spark.apache.org/docs/2.0.0/api/java/overview-summary.html), the package org.apache.spark.annotation is removed. Does anyone know if it's moved to another package? Or how to call developerAPI with absence of the annotation? Thanks. Cheers, Liren
