Hi all, I have a UDTF that returns fields from an XML/SerDe based table. So I have to return varying number of fields from the UDTF based on the number of xpath's in the query file. I am not sure how to access the values of the parameters in the initialize() method of the UDTF. It only has the ObjectInspector array. The UDTF itself works fine if I always return a fixed number of fields.
Something like select * from myudtf(xpathsfile); Should return as many fields as there are xpaths in the file. Or I can also modify the UDTF to take in a parameter for the number of fields, like select * from myudtf(5,xpathsfile); I am kind of against a wall here. Any help is appreciated. Regards, Murali.
