             Summary: GenericUDF.getFuncName breaks with UDF Classnames less than 10 characters
                 Key: HIVE-14759
                 URL: https://issues.apache.org/jira/browse/HIVE-14759
             Project: Hive
          Issue Type: Bug
          Components: UDF
    Affects Versions: 2.1.0
            Reporter: Clemens Valiente
            Assignee: Clemens Valiente
            Priority: Trivial


{code}
return getClass().getSimpleName().substring(10).toLowerCase();
{code}
causes
{code}
java.lang.StringIndexOutOfBoundsException: String index out of range: -2
    at java.lang.String.substring(String.java:1875)
    at org.apache.hadoop.hive.ql.udf.generic.GenericUDF.getFuncName(GenericUDF.java:258)
{code}

if the Classname of my UDF is less than 10 characters.
this was probably to remove "GenericUDF" from the classname but causes issues if the class doesn't start with it.
