Hi,
I wrote several UDF to handle a string typed column. However, when I feed a
constant value to the UDF, it's not recognizing it.
What went wrong ? How can I fix it ?
Example SQL: SELECT MBB("Polygon ((0 1, 1 1, 0 1, 0 0))") FROM myTable
limit 5;
MBB(Text) returns Text value
However the error I get is like this:
FAILED: SemanticException [Error 10014]: Line 1:7 Wrong arguments '"Polygon
((0 1, 1 1, 0 1, 0 0))"': org.apache.hadoop.hive.ql.metadata.HiveException:

edu.emory.cci.hive.udf.UDFMBB with arguments {Polygon ((0 1, 1 1, 0 1, 0
0)):org.apache.hadoop.io.Text} of size 1
