Subject Cannot submit Tez application
Date Sun, 11 May 2014 03:26:11 GMT
Hi,
 
I built Tez-0.5 against hadoop-2.4.0, and I've put all jars to the HDFS, configured tez-site.xml
correctly.
 
Hive version is 0.13.0, I've set hive.execution.engine to tez in hive-site.xml
 
then I submit the hive query, got the following exception:
 
2014-05-11 11:13:08,533 ERROR [main]: exec.Task (TezTask.java:execute(185)) - Failed to execute
tez graph.
java.lang.IllegalStateException: Vertex: Reducer 4 already has group input with name:Union
