Description

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
