I've changed from HDInsight 3.1 to HDInsight 3.2 (Tez 0.5.2, Hive 0.14.0) and started getting a following error while executing hive query. When I excluded columns that contained data for MAP or ARRAY - everything was fine.

Unexpected exception: org.apache.hadoop.hive.serde2.lazybinary.LazyBinaryMap cannot be cast to java.util.Map at org.apache.hadoop.hive.ql.exec.MapJoinOperator.processOp(MapJoinOperator.java:311) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815)

Vertex killed as other vertex failed. failedTasks:0, Vertex vertex_1424340440772_0043_1_02 [Reducer 2] killed/failed due to:null

What has solved this problem for me is setting "hive.mapjoin.optimized.hashtable" to false.
