prefer_plain_java: true
Description
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:
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 public boolean resetValues() ^ overridden method does not throw org.apache.drill.exec.exception.SchemaChangeException (compiler.err.override.meth.doesnt.throw)
