    Do you have the below UDF’s converted into Spark SQL UDF’S(BY Implementing UDF1,UDF2,…)


    I know we can access hive udf functions from Spark SQL. However we need these functions re-written in default Spark SQL native API’s

    • jeromebanks says:

      You can access the UDF’s from Spark, simply by running hiveContext.sql(” CREATE TEMPORARY FUNCTION collect AS ….”);
      There were issues with earlier versions of Spark (before 1.5) accessing UDF’s, but now it should work fine.

      I don’t believe there is any intrinsic need to port to Spark Native API’s (the Java Hive versions work fine; there aren’t any major performance problems.) I have been porting some of Brickhouse to Spark and Scala, (mostly around XUnits and Sketch sets), but this is more to support Scala’s functional paradigm. Unfortunately, this is not currently open-sourced
