Min Zhou updated HIVE-322: -------------------------- Description: 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 patch that soon. was: CREATE TEMPORARY FUNCTION strlen AS 'com.taobao.hadoop.hive.udf.UdfStringLength' I found the ClassLoader cannot load my UDF when doing FunctionTask, because the ClassLoader hasnot append its classpaths on-the-fly yet.
