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

             Summary: Analyze table may fail when prefer_plain_java is set to true on codegen for resetValues 
                 Key: DRILL-7173
                 URL: https://issues.apache.org/jira/browse/DRILL-7173
             Project: Apache Drill
          Issue Type: Improvement
          Components: Execution - Codegen
    Affects Versions: 1.15.0
         Environment: *prefer_plain_java: true*

 
            Reporter: Boaz Ben-Zvi
             Fix For: 1.17.0


  The *prefer_plain_java* compile option is useful for debugging of generated code (can be set in dril-override.conf; the default value is false). When set to true, some "analyze table" calls generate code that fails due to addition of a SchemaChangeException which is not in the Streaming Aggr template.

For example:
{noformat}
apache drill (dfs.tmp)> create table lineitem3 as select * from cp.`tpch/lineitem.parquet`;
+----------+---------------------------+
| Fragment | Number of records written |
+----------+---------------------------+
| 0_0 | 60175 |
+----------+---------------------------+
1 row selected (2.06 seconds)
apache drill (dfs.tmp)> analyze table lineitem3 compute statistics;
Error: SYSTEM ERROR: CompileException: File 'org.apache.drill.exec.compile.DrillJavaFileObject[StreamingAggregatorGen4.java]', Line 7869, Column 20: StreamingAggregatorGen4.java:7869: error: resetValues() in org.apache.drill.exec.test.generated.StreamingAggregatorGen4 cannot override resetValues() in org.apache.drill.exec.physical.impl.aggregate.StreamingAggTemplate
