Vihang Karajgaonkar commented on HIVE-17272: -------------------------------------------- +1 LGTM. I think the other way to fix this would have been in {{Vectorizer#validateInputFormatAndSchemaEvolution}} and return false if {{pathToPartitionInfo}} is empty. > when hive.vectorized.execution.enabled is true, query on empty partitioned > table fails with NPE > ----------------------------------------------------------------------------------------------- > > Key: HIVE-17272 > URL: https://issues.apache.org/jira/browse/HIVE-17272 > Project: Hive > Issue Type: Bug > Components: Query Planning > Affects Versions: 2.1.1 > Reporter: Aihua Xu > Assignee: Aihua Xu > Attachments: HIVE-17272.2.patch > > > {noformat} > set hive.vectorized.execution.enabled=true; > CREATE TABLE `tab`(`x` int) PARTITIONED BY ( `y` int) stored as parquet; > select * from tab t1 join tab t2 where t1.x=t2.x; > {noformat} > The query fails with the following exception. > {noformat} > Caused by: java.lang.NullPointerException > at > org.apache.hadoop.hive.ql.exec.vector.VectorMapOperator.createAndInitPartitionContext(VectorMapOperator.java:386) > ~[hive-exec-2.3.0.jar:2.3.0] > at > org.apache.hadoop.hive.ql.exec.vector.VectorMapOperator.internalSetChildren(VectorMapOperator.java:559) > ~[hive-exec-2.3.0.jar:2.3.0] > at > org.apache.hadoop.hive.ql.exec.vector.VectorMapOperator.setChildren(VectorMapOperator.java:474) > ~[hive-exec-2.3.0.jar:2.3.0] > at > org.apache.hadoop.hive.ql.exec.mr.ExecMapper.configure(ExecMapper.java:106) > ~[hive-exec-2.3.0.jar:2.3.0] > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > ~[?:1.8.0_101] > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > ~[?:1.8.0_101] > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > ~[?:1.8.0_101] > at java.lang.reflect.Method.invoke(Method.java:498) ~[?:1.8.0_101] > at > org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:106) > ~[hadoop-common-2.6.0.jar:?] > at > org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:75) > ~[hadoop-common-2.6.0.jar:?] > at > org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:133) > ~[hadoop-common-2.6.0.jar:?] > at org.apache.hadoop.mapred.MapRunner.configure(MapRunner.java:34) > ~[hadoop-core-2.6.0-mr1-cdh5.4.2.jar:?] > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > ~[?:1.8.0_101] > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > ~[?:1.8.0_101] > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > ~[?:1.8.0_101] > at java.lang.reflect.Method.invoke(Method.java:498) ~[?:1.8.0_101] > at > org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:106) > ~[hadoop-common-2.6.0.jar:?] > at > org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:75) > ~[hadoop-common-2.6.0.jar:?] > at > org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:133) > ~[hadoop-common-2.6.0.jar:?] > at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:413) > ~[hadoop-core-2.6.0-mr1-cdh5.4.2.jar:?] > at org.apache.hadoop.mapred.MapTask.run(MapTask.java:332) > ~[hadoop-core-2.6.0-mr1-cdh5.4.2.jar:?] > at > org.apache.hadoop.mapred.LocalJobRunner$Job$MapTaskRunnable.run(LocalJobRunner.java:268) > ~[hadoop-core-2.6.0-mr1-cdh5.4.2.jar:?] > at > java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) > ~[?:1.8.0_101] > at java.util.concurrent.FutureTask.run(FutureTask.java:266) > ~[?:1.8.0_101] > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > ~[?:1.8.0_101] > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > ~[?:1.8.0_101] > at java.lang.Thread.run(Thread.java:745) ~[?:1.8.0_101] > {noformat} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
