>             Project: Hive
>          Issue Type: Bug
>          Components: Standalone Metastore
>    Affects Versions: 4.0.0-alpha-1
>            Reporter: Zhihua Deng
>            Assignee: Zhihua Deng
>            Priority: Major

> When an old Hive Metastore client issues listPartitionsByExpr against the 
> lastest HMS, an exception would be thrown:
>  
> {noformat}
> MetaException(message:Unable to find class: 
> )

> org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$get_partitions_by_expr_result$get_partitions_by_expr_resultStandardScheme.read(ThriftHiveMetastore.java)

> org.apache.hadoop.hive.metastore.HiveMetaStoreClient.listPartitionsByExpr(HiveMetaStoreClient.java:1488){noformat}
> This was caused by a gap between old client and server on (de)serializing the 
> expression. In old client, we don’t stream the expression’s class type into 
> bytes, while the server should read the class type from serialized bytes 
> firstly, which makes the trouble. Other APIs that need to (de)serialize 
> expression may be suffered as well.
