Hi,
I've written a UDF to convert currency values which are stored in an external
table as double together with the currency type as string.
The currency udf extends UDF and has one method to convert the value:
public DoubleWritable evaluate(DoubleWritable value, Text baseCurrency, Text
targetCurrency)
In the select statement I call the function. value and currency are defined
with the right types in the external
table:convert_currency(value,currency,'EUR')
and it throws the following error:Wrong arguments ''EUR'': No matching method
for class com.xxx.hive.udf.UDFCurrencyConverter with (double, string, string).
Possible choices: _FUNC_(org.apache.hadoop.io.DoubleWritable, string, string)
That is with Hive version 0.8.1.6
Has anybody a hint what is going wrong?
Thanks,Oliver
