[GitHub] [samza] shanthoosh opened a new pull request #1192: SAMZA-2354: Improve UDF discovery in samza-sql.

shanthoosh opened a new pull request #1192: SAMZA-2354: Improve UDF discovery in samza-sql.
URL: https://github.com/apache/samza/pull/1192
 
 
   This patch is comprised of following changes: 
   
   1. Currently to plugin a udf implementation into samza-sql engine, users have to set the fully qualified class name of their UDF implementation in `samza.sql.udfClasses` configuration.  Any user error made in defining the fully-qualified name of udf-class configuration can only be identified  at run-time. This patch addresses this problem by using reflection to find all the samza-sql UDF implementations available in the class-path of the samza-sql application.
   2. Removes the ConfigBasedUdfResolver class and it's associated usages. 
   3. Adds  unit-tests for the newly introduced `UDFResolver` implementation.
