hive table error

[#1]

I created a hive table as follows :

CREATE EXTERNAL TABLE tweetdata(created_at STRING,
text STRING,
  person STRUCT< 
     screen_name:STRING,
     name:STRING,
     locations:STRING,
     description:STRING,
     created_at:STRING,
     followers_count:INT,
     url:STRING>
) ROW FORMAT SERDE 'com.cloudera.hive.serde.JSONSerDe' location '/user/flume/tweets';

but I am getting errors doing selecting

iam using HDP2.5

hive>
    > describe tweetdata;

I just created an empty simple table with no structures and its showing the same behavior .what am I missing here?

Logging initialized using configuration in file:/etc/hive/2.5.0.0-1245/0/hive-log4j.properties
hive> create external table load_tweets(id BIGINT,text STRING)
    >      ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
    >      LOCATION '/user/flume/tweets';
OK

hive> describe load_tweets;

I fixed this error by using another serde "org.openx.data.jsonserde.JsonSerDe "
