Apache Spark reassigned SPARK-35321:
------------------------------------
Assignee: Apache Spark
> Spark 3.x can't talk to HMS 1.2.x and lower due to get_all_functions Thrift
> API missing
> ---------------------------------------------------------------------------------------
>
> Key: SPARK-35321
> URL: https://issues.apache.org/jira/browse/SPARK-35321
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.2, 3.1.1, 3.2.0
> Reporter: Chao Sun
> Assignee: Apache Spark
> Priority: Major
>
> https://issues.apache.org/jira/browse/HIVE-10319 introduced a new API
> {{get_all_functions}} which is only supported in Hive 1.3.0/2.0.0 and up.
> This is called when creating a new {{Hive}} object:
> {code}
> private Hive(HiveConf c, boolean doRegisterAllFns) throws HiveException {
> conf = c;
> if (doRegisterAllFns) {
> registerAllFunctionsOnce();
> }
> }
> {code}
> {{registerAllFunctionsOnce}} will reload all the permanent functions by
> calling the {{get_all_functions}} API from the megastore. In Spark, we always
> pass {{doRegisterAllFns}} as true, and this will cause failure:
> {code}
> Caused by: org.apache.hadoop.hive.ql.metadata.HiveException:
> org.apache.thrift.TApplicationException: Invalid method name:
> 'get_all_functions'
> at
> org.apache.hadoop.hive.ql.metadata.Hive.getAllFunctions(Hive.java:3897)
> at
> org.apache.hadoop.hive.ql.metadata.Hive.reloadFunctions(Hive.java:248)
> at
> org.apache.hadoop.hive.ql.metadata.Hive.registerAllFunctionsOnce(Hive.java:231)
> ... 96 more
> Caused by: org.apache.thrift.TApplicationException: Invalid method name:

> at
> org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.get_all_functions(ThriftHiveMetastore.java:3833)
> {code}
> It looks like Spark doesn't really need to call {{registerAllFunctionsOnce}}
> since it loads the Hive permanent function directly from HMS API. The Hive
> {{FunctionRegistry}} is only used for loading Hive built-in functions.
