Hive metastore doesn’t support stats on container types

hive> CREATE TABLE `test_map_text`(`id` string,`score` map<string,int>) ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe' WITH SERDEPROPERTIES ( 'colelction.delim'=',','field.delim'='|','mapkey.delim'=':','serializaion.format'='|') STORED AS TEXTFILE;
hive> LOAD DATA INPATH '/tmp/map.text' INTO TABLE test_map.text;
This is my test_map.txt at HDFS location
