---------------------------------

             Summary: JsonSerDe does not support array as map's value
                 Key: HIVE-16526
                 URL: https://issues.apache.org/jira/browse/HIVE-16526
             Project: Hive
          Issue Type: Bug
          Components: HCatalog, Serializers/Deserializers
    Affects Versions: 1.2.1
            Reporter: Yulei Yang
            Priority: Minor


To reproduce the issue do the following:

CREATE TABLE test (
    store map<string,array<string>>
)
ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
STORED AS TEXTFILE;
load data local inpath '/path/to/s6.txt' overwrite into table test;
select * from test;

The data for s6.txt is below:
{"store":{"fruit":["weight","8","type","apple"]}}
{"store":{"fruit":["weight","9","type","orange"]}}

Error log is:
