@wenfang6 We insert a fake row to support native write, but it falls back to the vanilla Spark writer here. It seems that isNativeApplicable is not set correctly. Does your code include this patch? And can you help to provide the reproduced sql? Thanks.

simple sql also has this error, like :

insert overwrite  table wen_test_par1 partition (ds = '2024-10-09') 
select * from wen_test;

gluten plan ：

== Fallback Summary ==
No fallback nodes

== Physical Plan ==
Execute InsertIntoHiveTable (4)
+- FakeRowAdaptor (3)
   +- ^ NativeScan hive dap_dev.wen_test (1)

we use spark 3.2.1

@wenfang6 Gluten native writer in spark 321 overwrite vanilla spark HiveFileFormat class. Therefore, you must ensure that the gluten jar is loaded prior to the vanilla spark jar. You can refer the this document to configure. Thanks.

l try it, but Still haven't use native write. plan like this

== Fallback Summary ==
No fallback nodes

== Physical Plan ==
CommandResult (1)
   +- Execute InsertIntoHiveTable (5)
      +- VeloxColumnarToRowExec (4)
         +- ^ NativeScan hive dap_dev.wen_test (2)

@wenfang6 Does the above issue is fixed based on this document ? Also native write doesn't support complex type. Does your sql contain complex type?

yeah, the above issue is fixed. but haven't use native write. sql doesn't contain complex type.

@wenfang6 Does this config spark.gluten.sql.native.writer.enabled enabled in your env? The default value is false.

l set the conf spark.gluten.sql.native.hive.writer.enabled=true

@wenfang6 Can you add some logging info here to determine why this line is not being executed?
