Emil Ibrishimov updated HIVE-620:
---------------------------------
Attachment: HIVE-620.1.patch
exprNodeFuncDesc's constructor now takes the function name as an argument and
uses it to look up the correct display name and all the other stuff.
Some tests had wrong display names, so I overwrote them.
> resolver does not pick the right function when more than one function points
> at it

> If we have more than one function for the same class,
> CREATE TEMPORARY FUNCTION testlength AS
> 'org.apache.hadoop.hive.ql.udf.UDFLength';
> CREATE TEMPORARY FUNCTION testlength2 AS
> 'org.apache.hadoop.hive.ql.udf.UDFLength';
> any one of them may get picked up while processing the other one:
> for example:
> explain select testlength(src.key) from src;
> may show testlength2 instead.
