我在Hive 0.11中使用Hadoop 0.20.2。我已成功插入配置單元表中的一些csv文件的配置單元/ hdfs。完美選擇並加入工作。當嘗試分析一些數據，我需要利用內置的蜂房一樣的功能：Hive內置函數不起作用
- SUBSTR
- TO_DATE
- 蘭特
- 等
例如：
select sid, request_id, to_date(times), to_unix_timestamp(times) from contents where sid = '5000000032066010373';
sid和請求ID是字符串這裏，次使用這些功能時，timestamp列 Unfortanetely我只得到錯誤（總是相同的錯誤堆棧）：

我到底錯在這裏做什麼？
SHOW FUNCTIONS;
讓我發現，這些功能在那裏...
你可以檢查，如果你有傑克遜核心ASL。？ – zsxwing
是的，版本1.8.8有... – Wolli
試圖降級到配置單元0.10.0，同樣的錯誤信息 – Wolli
