             Summary: Loading snapshot testdata failed

I tried to load a snapshot of testdata and encountered this failure:
{code}

{code}
Looking into the error log file, the failure is
{code}

ImpalaBeeswaxException: ImpalaBeeswaxException:
 Query aborted:ImpalaRuntimeException: Error making 'dropTable' RPC to Hive Metastore: 
CAUSED BY: MetaException: Cannot drop table as it is used in the following materialized views [functional_seq_record_snap.materialized_view]
{code}
The DROP TABLE statement is executed before each CREATE TABLE statment, e.g.
{code:sql}
DROP TABLE IF EXISTS functional_seq_record_snap.insert_only_transactional_table;
CREATE  TABLE IF NOT EXISTS functional_seq_record_snap.insert_only_transactional_table (
col1 int
)
STORED AS SEQUENCEFILE
LOCATION '/test-warehouse/managed/functional_seq_record_snap.db/insert_only_transactional_table_seq_record_snap'
TBLPROPERTIES (
'transactional_properties' = 'insert_only',
'transactional' = 'true'
);
{code}
The MV is supposed to be created later in load-functional-query-exhaustive-hive-generated-seq-snap-record.sql:
{code:sql}
DROP TABLE IF EXISTS functional_seq_record_snap.materialized_view;
-- The create materialized view command is moved down so that the database's
-- managed directory has been created. Otherwise the command would fail. This
-- is a bug in Hive.
CREATE MATERIALIZED VIEW IF NOT EXISTS functional_seq_record_snap.materialized_view
  AS SELECT * FROM functional_seq_record_snap.insert_only_transactional_table;
{code}

As I'm loading the snapshot which is done by loading HMS snapshot and then loading the HDFS snapshot, I think those CREATE/DROP statements should be skipped.
