Tez is a dag based system, it's aware of all opération in such a way that it optimizes these operations before starting execution. mapreduce model simply states that any computation can be performed by two kinds of computation steps – a map step and a reduce step. one pair of map and reduce does one level of aggregation over the data. complex computations typically require multiple such. Info : tez session hasn't been created yet. opening session aftewards, there is nothing shows up and it seems that something wrong with "tez" in addition, i'm trying to run the same query using "mapreduce" instead of "tez" and mapreduce job hangs as well (start hive cli using hive hiveconf hive.execution.engine=mr. Any query with the 'where' clause fails. if i set the execution engine to tez using the command, the queries run fine. set hive.execution.engine=tez; not sure what is happening and why it is failing when the hive.execution.engine=mr (which i believe is the default)? edit: i setup a 3 node cluster and used ambari to install and setup hdp 2.1.
