Hi
with sqlContext we can register a UDF like
this: sqlContext.udf.register("sample_fn", sample_fn _ )
But this UDF is limited to that particular sqlContext only. I wish to make
the registration persistent, so that I can access the same UDF in any
subsequent sqlcontext.
Or is there any other way to register UDFs in sparkSQL so that they remain
persistent?Regards Lokesh
