Hi All, I am hitting the below exception while running a SELECT statement in LLAP. Same query works on Tez.. The environment is Hive 1.2 and HDP 2.6.1. Any clues on what could be wrong? 2017-08-16 20:37:22,269 [INFO] [Dispatcher thread {Central}] |HistoryEventHandler.criticalEvents|: [HISTORY][DAG:dag_1502817965713_0066_21][Event:TASK_ATTEMPT_FINISHED]: vertexName=Map 6, taskAttemptId=attempt_1502817965713_0066_21_04_000009_0, creationTime=1502915841055, allocationTime=1502915841247, startTime=1502915841248, finishTime=1502915842269, timeTaken=1021, status=FAILED, taskFailureType=FATAL, errorEnum=APPLICATION_ERROR, diagnostics=Error: Error while running task ( failure ) : org.apache.hadoop.hive.ql.metadata.HiveException: java.io.IOException: java.io.IOException: java.lang.AssertionError: Unexpected refCount -1: 0x5b87f493(-1) at org.apache.hadoop.hive.ql.exec.tez.MapRecordSource.pushRecord(MapRecordSource.java:74) at org.apache.hadoop.hive.ql.exec.tez.MapRecordProcessor.run(MapRecordProcessor.java:419) at org.apache.hadoop.hive.ql.exec.tez.TezProcessor.initializeAndRunProcessor(TezProcessor.java:189) at org.apache.hadoop.hive.ql.exec.tez.TezProcessor.run(TezProcessor.java:172) at org.apache.tez.runtime.LogicalIOProcessorRuntimeTask.run(LogicalIOProcessorRuntimeTask.java:370) at org.apache.tez.runtime.task.TaskRunner2Callable$1.run(TaskRunner2Callable.java:73) at org.apache.tez.runtime.task.TaskRunner2Callable$1.run(TaskRunner2Callable.java:61) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1866) at org.apache.tez.runtime.task.TaskRunner2Callable.callInternal(TaskRunner2Callable.java:61) at org.apache.tez.runtime.task.TaskRunner2Callable.callInternal(TaskRunner2Callable.java:37) at org.apache.tez.common.CallableWithNdc.call(CallableWithNdc.java:36) at org.apache.hadoop.hive.llap.daemon.impl.StatsRecordingThreadPool$WrappedCallable.call(StatsRecordingThreadPool.java:110) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.io.IOException: java.io.IOException: java.lang.AssertionError: Unexpected refCount -1: 0x5b87f493(-1) at org.apache.hadoop.hive.io.HiveIOExceptionHandlerChain.handleRecordReaderNextException(HiveIOExceptionHandlerChain.java:121) at org.apache.hadoop.hive.io.HiveIOExceptionHandlerUtil.handleRecordReaderNextException(HiveIOExceptionHandlerUtil.java:77) at org.apache.hadoop.hive.ql.io.HiveContextAwareRecordReader.doNext(HiveContextAwareRecordReader.java:355) at org.apache.hadoop.hive.ql.io.HiveRecordReader.doNext(HiveRecordReader.java:79) at org.apache.hadoop.hive.ql.io.HiveRecordReader.doNext(HiveRecordReader.java:33) at org.apache.hadoop.hive.ql.io.HiveContextAwareRecordReader.next(HiveContextAwareRecordReader.java:116) at org.apache.hadoop.mapred.split.TezGroupedSplitsInputFormat$TezGroupedSplitsRecordReader.next(TezGroupedSplitsInputFormat.java:151) at org.apache.tez.mapreduce.lib.MRReaderMapred.next(MRReaderMapred.java:116) at org.apache.hadoop.hive.ql.exec.tez.MapRecordSource.pushRecord(MapRecordSource.java:62) ... 17 more<br> ...

The original processor is working fine, but the new target processor throws above error even though the script-body is same (copy pasted). Am on Apache Nifi 1.1 (HDF 2.1.0). Please see attached screenshots.screen-shot-2017-06-06-at-124431-pm.png Intent is to modify the original script-body and have a new Processor with new logic working parallel to original Processor. ...
