Subject Re: UDF for lateral views
Date Thu, 18 Jan 2018 03:16:47 GMT
According to this blog (
http://phoenix-hbase.blogspot.in/2013/04/how-to-add-your-own-built-in-function.html),
evaluate(...) is responsible for processing the input state of the row and
filling up ImmutableBytesWritable pointer with transformed row.
Did not find any references that'll support returning multiple rows for
each input row. Does anyone know if UDF framework can support that?
