Aman Sinha created DRILL-3947: --------------------------------- Summary: IndexOutOfBoundsException for pruning on date column (at large scale) Key: DRILL-3947 URL: https://issues.apache.org/jira/browse/DRILL-3947 Project: Apache Drill Issue Type: Bug Components: Query Planning & Optimization Affects Versions: 1.2.0 Reporter: Aman Sinha Assignee: Aman Sinha
When a large table (about 52 B records, 10K files, created with CTAS auto-partitioning) partitioned by a 'date' column, partition pruning is encountering an error. At smaller scales, partition pruning succeeds. At this time, the problem seems specific to date columns only. This column is a nullable column and has NULL values in the data. Here's the query: {code} explain plan for select count(*) from `table` where `date` = '2015-07-01'; {code} Here's the error stack: {code} WARN o.a.d.e.p.l.partition.PruneScanRule - Exception while trying to prune partition. java.lang.IndexOutOfBoundsException: index: 4096, length: 1 (expected: range(0, 4096)) at io.netty.buffer.DrillBuf.checkIndexD(DrillBuf.java:189) ~[drill-java-exec-1.2.0.jar:4.0.27.Final] at io.netty.buffer.DrillBuf.chk(DrillBuf.java:211) ~[drill-java-exec-1.2.0.jar:4.0.27.Final] at io.netty.buffer.DrillBuf.setByte(DrillBuf.java:612) ~[drill-java-exec-1.2.0.jar:4.0.27.Final] at org.apache.drill.exec.vector.UInt1Vector$Mutator.set(UInt1Vector.java:411) ~[drill-java-exec-1.2.0.jar:1.2.0] at org.apache.drill.exec.vector.NullableDateVector$Mutator.set(NullableDateVector.java:440) ~[drill-java-exec-1.2.0.jar:1.2.0] at org.apache.drill.exec.store.parquet.ParquetGroupScan.populatePruningVector(ParquetGroupScan.java:420) ~[drill-java-exec-1.2.0.jar:1.2.0] at org.apache.drill.exec.planner.ParquetPartitionDescriptor.populatePartitionVectors(ParquetPartitionDescriptor.java:96) ~[drill-java-exec-1.2.0.jar:1.2.0] at org.apache.drill.exec.planner.logical.partition.PruneScanRule.doOnMatch(PruneScanRule.java:212) ~[drill-java-exec-1.2.0.jar:1.2.0] at org.apache.drill.exec.planner.logical.partition.ParquetPruneScanRule$2.onMatch(ParquetPruneScanRule.java:87) [drill-java-exec-1.2.0.jar:1.2.0] at org.apache.calcite.plan.volcano.VolcanoRuleCall.onMatch(VolcanoRuleCall.java:228) [calcite-core-1.4.0-drill-r5.jar:1.4.0-drill-r5] at org.apache.calcite.plan.volcano.VolcanoPlanner.findBestExp(VolcanoPlanner.java:808) [calcite-core-1.4.0-drill-r5.jar:1.4.0-drill-r5] {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
