[jira] [Created] (IMPALA-15072) Exclude OPTIMIZE TABLE maintenance operation from lineage graph
Noémi Pap-Takács created IMPALA-15072:
-----------------------------------------
Summary: Exclude OPTIMIZE TABLE maintenance operation from lineage graph
Key: IMPALA-15072
URL: https://issues.apache.org/jira/browse/IMPALA-15072
Project: IMPALA
Issue Type: Bug
Reporter: Noémi Pap-Takács
Assignee: Noémi Pap-Takács
Running OPTIMIZE TABLE on Iceberg V3 tables migrated from V2 throws an IllegalStateException in ColumnLineageGraph:
{noformat}
java.lang.RuntimeException: java.lang.IllegalStateException at org.apache.impala.service.Frontend.getTExecRequestWithFallback(Frontend.java:2473) at org.apache.impala.service.Frontend.createExecRequest(Frontend.java:2140) at org.apache.impala.service.JniFrontend.createExecRequest(JniFrontend.java:180) Caused by: java.lang.IllegalStateException at com.google.common.base.Preconditions.checkState(Preconditions.java:497) at org.apache.impala.analysis.ColumnLineageGraph.computeProjectionDependencies(ColumnLineageGraph.java:637) at org.apache.impala.analysis.ColumnLineageGraph.computeLineageGraph(ColumnLineageGraph.java:607) at org.apache.impala.planner.Planner.createPlanFragments(Planner.java:281) at org.apache.impala.planner.Planner.createPlans(Planner.java:314) at org.apache.impala.service.Frontend.createExecRequest(Frontend.java:2078){noformat}
The Precondition check
{code:java}
Preconditions.checkState(resultExprs.size() == targetColumnLabels_.size());{code}
fails because V3 tables have 2 hidden columns: {{_file_row_id}} and {{_file_last_updated_sequence_number.}}
'targetColumnLabels_' contains them but 'resultExprs' filters out hidden columns.
Proposed solution:
We could exclude OPTIMIZE TABLE from the lineage graph, since it is a maintenance operation that unnecessarily pollutes the graph.
