Hi, I got the attached error on a map-side join where a serialized table contains an array column.
When setting map-side join off via setting hive.mapjoin.optimized.hashtable=false, exceptions do not occur. It seems that a wrong ObjectInspector was set at CommonJoinOperator#initializeOp. I am using Hive 1.0.0 (Tez 0.6) on Hadoop 2.6.0. I found a similar report at http://stackoverflow.com/questions/28606244/issues-upgrading-to-hdinsight-3-2-hive-0-14-0-tez-0-5-2 Is this a known issue/bug? Thanks, Makoto ------------------------------------------------------------ task:java.lang.RuntimeException: java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while processing row {"gid":1,"userid":4422,"movieid":1213,"rating":5} at org.apache.hadoop.hive.ql.exec.tez.TezProcessor.initializeAndRunProcessor(TezProcessor.java:186) at org.apache.hadoop.hive.ql.exec.tez.TezProcessor.run(TezProcessor.java:138) at org.apache.tez.runtime.LogicalIOProcessorRuntimeTask.run(LogicalIOProcessorRuntimeTask.java:324) at org.apache.tez.runtime.task.TezTaskRunner$TaskRunnerCallable$1.run(TezTaskRunner.java:176) at org.apache.tez.runtime.task.TezTaskRunner$TaskRunnerCallable$1.run(TezTaskRunner.java:168) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1628) at org.apache.tez.runtime.task.TezTaskRunner$TaskRunnerCallable.call(TezTaskRunner.java:168) at org.apache.tez.runtime.task.TezTaskRunner$TaskRunnerCallable.call(TezTaskRunner.java:163) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:722) Caused by: java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while processing row {"gid":1,"userid":4422,"movieid":1213,"rating":5} at org.apache.hadoop.hive.ql.exec.tez.MapRecordSource.processRow(MapRecordSource.java:91) at org.apache.hadoop.hive.ql.exec.tez.MapRecordSource.pushRecord(MapRecordSource.java:68) at org.apache.hadoop.hive.ql.exec.tez.MapRecordProcessor.run(MapRecordProcessor.java:294) at org.apache.hadoop.hive.ql.exec.tez.TezProcessor.initializeAndRunProcessor(TezProcessor.java:163) ... 14 more Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while processing row {"gid":1,"userid":4422,"movieid":1213,"rating":5} at org.apache.hadoop.hive.ql.exec.MapOperator.process(MapOperator.java:503) at org.apache.hadoop.hive.ql.exec.tez.MapRecordSource.processRow(MapRecordSource.java:83) ... 17 more Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Unexpected exception: Unexpected exception: org.apache.hadoop.hive.serde2.lazybinary.LazyBinaryArray cannot be cast to [Ljava.lang.Object; at org.apache.hadoop.hive.ql.exec.MapJoinOperator.processOp(MapJoinOperator.java:311) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815) at org.apache.hadoop.hive.ql.exec.SelectOperator.processOp(SelectOperator.java:84) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815) at org.apache.hadoop.hive.ql.exec.FilterOperator.processOp(FilterOperator.java:120) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815) at org.apache.hadoop.hive.ql.exec.TableScanOperator.processOp(TableScanOperator.java:95) at org.apache.hadoop.hive.ql.exec.MapOperator$MapOpCtx.forward(MapOperator.java:157) at org.apache.hadoop.hive.ql.exec.MapOperator.process(MapOperator.java:493) ... 18 more Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Unexpected exception: org.apache.hadoop.hive.serde2.lazybinary.LazyBinaryArray cannot be cast to [Ljava.lang.Object; at org.apache.hadoop.hive.ql.exec.MapJoinOperator.processOp(MapJoinOperator.java:311) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815) at org.apache.hadoop.hive.ql.exec.SelectOperator.processOp(SelectOperator.java:84) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815) at org.apache.hadoop.hive.ql.exec.CommonJoinOperator.internalForward(CommonJoinOperator.java:638) at org.apache.hadoop.hive.ql.exec.CommonJoinOperator.genAllOneUniqueJoinObject(CommonJoinOperator.java:670) at org.apache.hadoop.hive.ql.exec.CommonJoinOperator.checkAndGenObject(CommonJoinOperator.java:748) at org.apache.hadoop.hive.ql.exec.MapJoinOperator.processOp(MapJoinOperator.java:299) ... 26 more Caused by: java.lang.ClassCastException: org.apache.hadoop.hive.serde2.lazybinary.LazyBinaryArray cannot be cast to [Ljava.lang.Object; at org.apache.hadoop.hive.serde2.objectinspector.StandardListObjectInspector.getListLength(StandardListObjectInspector.java:90) at org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorUtils.copyToStandardObject(ObjectInspectorUtils.java:312) at org.apache.hadoop.hive.ql.exec.JoinUtil.computeValues(JoinUtil.java:193) at org.apache.hadoop.hive.ql.exec.CommonJoinOperator.getFilteredValue(CommonJoinOperator.java:408) at org.apache.hadoop.hive.ql.exec.MapJoinOperator.processOp(MapJoinOperator.java:295) ... 33 more The entire log can be found at https://gist.github.com/myui/55655da79ef1a9f58005 ------------------------------------------------------------
