Min Zhou commented on HIVE-322:
-------------------------------
The add/delete/list <resource> ...' command is only supported by CLI mode right
now. It puts a file path into a map, then be retrieved and added into hadoop's
tmpfiles by ExecDriver's initialize method, but you know, this method won't be
called by Thrift Server mode.
Have you considered adding this feature to Thrift Server mode?

> I found the ClassLoader cannot load my UDF when doing FunctionTask, because
> the ClassLoader hasnot append its classpaths on-the-fly yet.
> The ExecDriver' s addToClassPath(String[] newPaths) method is the only entry
> for ClassLoader dynamically append its classhpaths (besides hadoop's
> GenericOptionsParser).
> But that function wasnot called before FunctionTask getting my UDF class by
> class name. I think this is the reason why I came across that failure.
> scenario description:
> I set a peroperty in hive-site.xml to configure the classpath of my udf.
> <property>
> <name>hive.aux.jars.path</name>
> <value>/home/hadoop/hdpsoft/hive-auxs/zhoumin.jar</value>
> </property>
> but failed to register it with a ClassNotFoundException when creating udf
> through the sql command.
> CREATE TEMPORARY FUNCTION strlen AS 'hadoop.hive.udf.UdfStringLength'
> I'll make a patch soon.
