@marmbrus I think hiveResults can be finded in two ways: 1. in dir
```sql/hive/src/test/resources/golden``` 2. driver.run(sql)
```
val hiveResults: Seq[Seq[String]] =
if (hiveCachedResults.size == queryList.size) {
logInfo(s"Using answer cache for test: $testCaseName")
hiveCachedResults
} else {
val hiveQueries = queryList.map(new TestHive.HiveQLQueryExecution(_))
```
when ```sql/hive/src/test/resources/golden``` is empty, it will execute MR
Task to generate, but it always throw error
```
- create table as with db name use backticks *** FAILED ***
Failed to generate golden answer for query:
Error: FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.mr.MapRedTask
org.apache.spark.sql.execution.QueryExecutionException: FAILED: Execution
Error, return code 1 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
```
Can you tell me the reason? Many thanks.
