Hi All
In HIVE, I would like to write a UDF that accepts a sequence of parameters. Due
to that the number of parameters is large and the particular function that I am
writing is specific to a set of tables (joined in some way in the SQL), I am
wondering if there is a way to pass the entire row
Can this be only used in regular select statement or also as arguments to UDF?
In this case, how shall I define my UDF/GenericUDF method signature to accept
column in this form? Will Hive automatically expand the column list and pass
them to customized UDF?
If there is any example, that would
le select .
