Kunal Khatua updated DRILL-6197: -------------------------------- Labels: ready-to-commit (was: ) > Duplicate entries in inputProfiles of minor fragments for specific operators > ---------------------------------------------------------------------------- > > Key: DRILL-6197 > URL: https://issues.apache.org/jira/browse/DRILL-6197 > Project: Apache Drill > Issue Type: Bug > Components: Execution - Monitoring > Affects Versions: 1.12.0 > Reporter: Kunal Khatua > Assignee: Kunal Khatua > Priority: Minor > Labels: ready-to-commit > Fix For: 1.13.0 > > Original Estimate: 24h > Remaining Estimate: 24h > > Minor fragments for the following operators show duplicate entries of the > inputProfile ({{org.apache.drill.exec.ops.OperatorStats}} instance) when > viewed in the Profile UI. > e.g > {code:json} > { > ... > "query": "select * from sys.version", > ... > [ ... > { > "inputProfile": [{ > "records": 0, > "batches": 0, > "schemas": 0 > }], > "operatorId": 0, > "operatorType": 13, > "setupNanos": 0, > "processNanos": 0, > "peakLocalMemoryAllocated": 27131904, > "waitNanos": 0 > }, > { > "inputProfile": [{ > "records": 1, > "batches": 1, > "schemas": 1 > }], > "operatorId": 0, > "operatorType": 13, > "setupNanos": 0, > "processNanos": 752448, > "peakLocalMemoryAllocated": 27131904, > "metric": [{ > "metricId": 0, > "longValue": 178 > }], > "waitNanos": 889492 > }] > ... > } > {code} > {{operatorType: 13}} is the screen operator, for which there can be only one > inputProfile. > It turns out that by default, all minor fragments' operators are provide a > list of inputProfiles by > {{org.apache.drill.exec.ops.FragmentStats.newOperatorStats(OpProfileDef, > BufferAllocator)}}. However, for the following 4 operators, the > {{org.apache.drill.exec.physical.impl.BaseRootExec}} constructors also inject > {{OperatorStats}}. > {code:java} > org.apache.drill.exec.proto.beans.CoreOperatorType.SCREEN > org.apache.drill.exec.proto.beans.CoreOperatorType.SINGLE_SENDER > org.apache.drill.exec.proto.beans.CoreOperatorType.BROADCAST_SENDER > org.apache.drill.exec.proto.beans.CoreOperatorType.HASH_PARTITION_SENDER > {code} > All updates to the inputProfiles are done by the latter, while the former > only reports zero values. > The workaround is to have {{org.apache.drill.exec.ops.FragmentStats}} skip > injecting the {{org.apache.drill.exec.ops.OperatorStats}} instance for these > operators -- This message was sent by Atlassian JIRA (v7.6.3#76005)
