Github user jihoonson commented on the pull request: https://github.com/apache/tajo/pull/929#issuecomment-194132955 Hi @eminency, I left some comments. In addition, I found the below error when I start a tajo cluster. I put the hive udf jar file on hdfs and specified it in tajo-site.xml. ``` 2016-03-09 14:34:06,613 FATAL org.apache.tajo.master.TajoMaster: Error starting TajoMaster org.apache.tajo.exception.TajoInternalError: internal error: unknown protocol: hdfs at org.apache.tajo.engine.function.hiveudf.HiveFunctionLoader.loadHiveUDFs(HiveFunctionLoader.java:70) at org.apache.tajo.master.TajoMaster.loadFunctions(TajoMaster.java:229) at org.apache.tajo.master.TajoMaster.serviceInit(TajoMaster.java:181) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.tajo.master.TajoMaster.main(TajoMaster.java:628) ```
