Ayush Saxena updated HIVE-18412: -------------------------------- Affects Version/s: 3.1.3 1.2.2 > FileSinkOperator thows NullPointerException > -------------------------------------------- > > Key: HIVE-18412 > URL: https://issues.apache.org/jira/browse/HIVE-18412 > Project: Hive > Issue Type: Bug > Components: Hive, Transactions > Affects Versions: 1.2.2, 3.1.3 > Environment: HDP2.6.1, Hive 1.2.1 > Reporter: Benjamin BONNET > Priority: Blocker > > Hi, > while executing a query (DELETE with a join) on an ACID table, I get a > NullPointerException in reducer. > See stack trace below. > According to FileSinkOperator source code, it seems that buckepMap transient > field is Null. > In my opinion, the only circumstance in which this field may be null is when > the involved FileSinkOperator has been serialized and then deserialized. > Actually, deserialization lets that transient reference uninitialized. > I checked source code for more recent versions (including Hive 2.x) but > everywhere that field may remain uninitialized (if FileSinkOperator is > serialized/deserialized). So I think that issue may concern any version of > Hive. > {noformat} > ERROR : Vertex failed, vertexName=Reducer 3, > vertexId=vertex_1513704146031_77754_2_05, diagnostics=[Task failed, > taskId=task_1513704146031_77754_2_05_000000, diagnostics=[TaskAttempt 0 > failed, info=[Error: Failure while running task:java > .lang.RuntimeException: java.lang.RuntimeException: > org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while > processing row (tag=0) > {"key":{"reducesinkkey0":{"transactionid":108117,"bucketid":0,"rowid":1114}},"value":{" > _col0":"2017","_col1":"10"}} > at > org.apache.hadoop.hive.ql.exec.tez.TezProcessor.initializeAndRunProcessor(TezProcessor.java:173) > at > org.apache.hadoop.hive.ql.exec.tez.TezProcessor.run(TezProcessor.java:139) > at > org.apache.tez.runtime.LogicalIOProcessorRuntimeTask.run(LogicalIOProcessorRuntimeTask.java:347) > at > org.apache.tez.runtime.task.TezTaskRunner$TaskRunnerCallable$1.run(TezTaskRunner.java:194) > at > org.apache.tez.runtime.task.TezTaskRunner$TaskRunnerCallable$1.run(TezTaskRunner.java:185) > at java.security.AccessController.doPrivileged(Native Method) > at javax.security.auth.Subject.doAs(Subject.java:422) > at > org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1866) > at > org.apache.tez.runtime.task.TezTaskRunner$TaskRunnerCallable.callInternal(TezTaskRunner.java:185) > at > org.apache.tez.runtime.task.TezTaskRunner$TaskRunnerCallable.callInternal(TezTaskRunner.java:181) > at org.apache.tez.common.CallableWithNdc.call(CallableWithNdc.java:36) > at java.util.concurrent.FutureTask.run(FutureTask.java:266) > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > at java.lang.Thread.run(Thread.java:745) > Caused by: java.lang.RuntimeException: > org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while > processing row (tag=0) > {"key":{"reducesinkkey0":{"transactionid":108117,"bucketid":0,"rowid":1114}},"value":{"_col0":"2017" > ,"_col1":"10"}} > at > org.apache.hadoop.hive.ql.exec.tez.ReduceRecordSource.pushRecord(ReduceRecordSource.java:284) > at > org.apache.hadoop.hive.ql.exec.tez.ReduceRecordProcessor.run(ReduceRecordProcessor.java:266) > at > org.apache.hadoop.hive.ql.exec.tez.TezProcessor.initializeAndRunProcessor(TezProcessor.java:150) > ... 14 more > Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime > Error while processing row (tag=0) > {"key":{"reducesinkkey0":{"transactionid":108117,"bucketid":0,"rowid":1114}},"value":{"_col0":"2017","_col1":"10"}} > at > org.apache.hadoop.hive.ql.exec.tez.ReduceRecordSource$GroupIterator.next(ReduceRecordSource.java:352) > at > org.apache.hadoop.hive.ql.exec.tez.ReduceRecordSource.pushRecord(ReduceRecordSource.java:274) > ... 16 more > Caused by: java.lang.NullPointerException > at > org.apache.hadoop.hive.ql.exec.FileSinkOperator.findWriterOffset(FileSinkOperator.java:830) > at > org.apache.hadoop.hive.ql.exec.FileSinkOperator.process(FileSinkOperator.java:758) > at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:841) > at > org.apache.hadoop.hive.ql.exec.SelectOperator.process(SelectOperator.java:88) > at > org.apache.hadoop.hive.ql.exec.tez.ReduceRecordSource$GroupIterator.next(ReduceRecordSource.java:343) > ... 17 more > ], TaskAttempt 1 failed, info=[Error: Failure while running > task:java.lang.RuntimeException: java.lang.RuntimeException: .... etc. > {noformat} -- This message was sent by Atlassian Jira (v8.20.10#820010)
