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.
