--------------------------------

             Summary:  Error while applying rule DrillPushProjectIntoScanRule:enumerable after
upgrading to 1.16
                 Key: DRILL-7802
                 URL: https://issues.apache.org/jira/browse/DRILL-7802
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning &amp; Optimization
    Affects Versions: 1.16.0
            Reporter: Dony Dong
         Attachments: error log.txt

We recently upgraded our Drill from 1.15 to 1.16.

After that, we found when querying some tables and empty tables, it will fail with below errors.

Error: SYSTEM ERROR: NoSuchElementException.

Caused by: org.apache.drill.exec.work.foreman.ForemanException: Unexpected exception during
fragment initialization: Error while applying rule DrillPushProjectIntoScanRule:enumerable,
args [rel#944215:LogicalProject.NONE.ANY([]).[](input=rel#944214:Subset#0.ENUMERABLE.ANY([]).[],$f0=0),
rel#944189:EnumerableTableScan.ENUMERABLE.ANY([]).[](table=[dfs, test_schema, dony_test])]

 

I copy the parquet files to another Drill 1.15, it works well.

Kindly advise  how to find the root cause and how to fix it.

 

Best Regards
