建立 HIVE-JSON 表

    -- 新增依賴 jar
    ADD JAR /data/tmp/liwei/hive-hcatalog-core-2.1.1.jar;


    DROP TABLE IF EXISTS `tmp.liwei_json_table`;
    CREATE TABLE IF NOT EXISTS tmp.liwei_json_table (
        `data_param`      map<string, string>,
        `account_param`   map<string, string>,
        `role_param`      map<string, string>,
        `event`           map<string, string>
    )
    comment 'liwei_json_table'
    ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
    STORED AS TEXTFILE
    ;


    --報錯  return code 1 from org.apache.hadoop.hive.ql.exec.ddltask. cannot validate serde: org.apache.hive.hcatalog.data.jsonserde
    --解決方案 ，新增對應 jar ，並對新增的 jar 授執行許可權
