Hello ! I send you this mail because I perform an hive query with Tez and it fails with a strange error : The error is like this : ### ERROR : Vertex failed, vertexName=Reducer 2, vertexId=vertex_1473870963805_157168_11_02, diagnostics=[Task failed, taskId=task_1473870963805_157168_11_02_000035, diagnostics=[TaskAttempt 0 failed, info=[Error: Failure while running task:java.lang.RuntimeException: java.lang.IllegalStateException: Was expecting dummy store operator but found: FS[26] at org.apache.hadoop.hive.ql.exec.tez.TezProcessor.initializeAndRunProcessor(TezProcessor.java:173)

It is done by doing a query using beeline and Tez as execution engine. I found some information here : http://svn.apache.org/viewvc/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/DummyStoreOperator.java?view=markup&pathrev=1423731 But I am not sure to fully understand yet why the error mention FS ? Is FS the file separator described here ? http://www.aivosto.com/vbtips/control-characters.html#FS Thank you in advance for your help o/ Best regards. Tale
