vrajat opened a new issue, #15045: URL: https://github.com/apache/pinot/issues/15045
A reproducer is available in https://github.com/apache/pinot/compare/master...vrajat:rv-oom-subquery-npe The issue is that subqueries make recursive calls to `BaseSingleStageBrokerRequestHandler.handleRequest`. The inner call clears the tracing context. When the outer call runs the reducer, no context is found and an NPE is thrown.  Stack Trace: ``` java.lang.NullPointerException: Cannot invoke "org.apache.pinot.spi.accounting.ThreadResourceUsageProvider.getThreadAllocatedBytes()" because the return value of "org.apache.pinot.core.accounting.PerQueryCPUMemAccountantFactory$PerQueryCPUMemResourceUsageAccountant.getThreadResourceUsageProvider()" is null at org.apache.pinot.core.accounting.PerQueryCPUMemAccountantFactory$PerQueryCPUMemResourceUsageAccountant.sampleThreadBytesAllocated(PerQueryCPUMemAccountantFactory.java:294) ~[classes/:?] at org.apache.pinot.core.accounting.PerQueryCPUMemAccountantFactory$PerQueryCPUMemResourceUsageAccountant.sampleUsage(PerQueryCPUMemAccountantFactory.java:238) ~[classes/:?] at org.apache.pinot.spi.trace.Tracing$ThreadAccountantOps.sample(Tracing.java:311) ~[classes/:?] at org.apache.pinot.spi.trace.Tracing$ThreadAccountantOps.sampleAndCheckInterruption(Tracing.java:352) ~[classes/:?] at org.apache.pinot.core.query.reduce.AggregationDataTableReducer.reduceWithIntermediateResult(AggregationDataTableReducer.java:88) ~[classes/:?] at org.apache.pinot.core.query.reduce.AggregationDataTableReducer.reduceAndSetResults(AggregationDataTableReducer.java:79) ~[classes/:?] at org.apache.pinot.core.query.reduce.BrokerReduceService.reduceOnDataTable(BrokerReduceService.java:159) ~[classes/:?] at org.apache.pinot.broker.requesthandler.SingleConnectionBrokerRequestHandler.processBrokerRequest(SingleConnectionBrokerRequestHandler.java:149) ~[classes/:?] at org.apache.pinot.broker.requesthandler.BaseSingleStageBrokerRequestHandler.handleRequest(BaseSingleStageBrokerRequestHandler.java:838) ~[classes/:?] at org.apache.pinot.broker.requesthandler.BaseBrokerRequestHandler.handleRequest(BaseBrokerRequestHandler.java:193) ~[classes/:?] at org.apache.pinot.broker.requesthandler.BrokerRequestHandlerDelegate.handleRequest(BrokerRequestHandlerDelegate.java:116) ~[classes/:?] at org.apache.pinot.broker.api.resources.PinotClientRequest.executeSqlQuery(PinotClientRequest.java:490) ~[classes/:?] at org.apache.pinot.broker.api.resources.PinotClientRequest.processSqlQueryPost(PinotClientRequest.java:177) ~[classes/:?] at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103) ~[?:?] at java.base/java.lang.reflect.Method.invoke(Method.java:580) ~[?:?] ``` -- This is an automated message from the Apache Git Service.
