Re: Registering custom UDAFs with HiveConetxt in SparkSQL, how?
Hello Shahab, Are you able to read tables created in Hive from Spark SQL ? If yes, how are you referring them ?

Shahab - This should do the trick until Hao's changes are out: sqlContext.sql(create temporary function foobar as 'com.myco.FoobarUDAF'); sqlContext.sql(select foobar(some_column) from some_table); This works without requiring to 'deploy' a JAR with the UDAF in it - just make sure the UDAF is in your project's classpath.
