UDF Question

UDF Question

I have a question regarding Impala UDF (written in Java).

Is there a way to call built-in Impala UDF function (i.e. effective_user) from Impala UDF ?

@Brian100 not in general.


We do actually expose the effective user via the FunctionContext for your use case though - see

Thanks !
When I call the effective_user from impala-shell it's working fine.
My question, how I can call the effective_user() from my implementation of UDF (written in Java) ?
