## What changes were proposed in this pull request? This PR is a follow-up of https://github.com/apache/spark/pull/21790 which causes a regression to show misleading warnings always at first invocation for all Hive function. Hive fallback lookup should not be warned. It's a normal process in function lookups. **CURRENT (Showing `NoSuchFunctionException` and working)** ```scala scala> sql("select histogram_numeric(a,2) from values(1) T(a)").show 19/06/02 22:02:10 WARN HiveSessionCatalog: Encountered a failure during looking up function: org.apache.spark.sql.catalyst.analysis.NoSuchFunctionException: Undefined function: 'histogram_numeric'. This function is neither a registered temporary function nor a permanent function registered in the database 'default'.; at org.apache.spark.sql.catalyst.catalog.SessionCatalog.failFunctionLookup(SessionCatalog.scala:1234) at org.apache.spark.sql.catalyst.catalog.SessionCatalog.lookupFunction(SessionCatalog.scala:1302) ... +------------------------+ |histogram_numeric( a, 2)| +------------------------+ | [[1.0, 1.0]]| +------------------------+ ``` ## How was this patch tested? Manually execute the above query. Closes #24773 from dongjoon-hyun/SPARK-24544. Authored-by: Dongjoon Hyun <dhyun@apple.com> Signed-off-by: Dongjoon Hyun <dhyun@apple.com> |
