Question

我可以连接到我的Hive Metastore，并进行DESCRIBE：

DESCRIBE sample_07;
Query 20131113_025614_00005_af2fx, RUNNING, 1 node, 2 splits
   Column    |  Type   | Null | Partition Key 
-------------+---------+------+---------------
 code        | varchar | true | false         
 description | varchar | true | false         
 total_emp   | bigint  | true | false         
 salary      | bigint  | true | false         
(4 rows)

但是，SELECT不起作用：

select * from sample_07;

正如您所知，我正在使用Hortonworks的沙盒，所以问题可能就是这个问题？还是窒息IP地址？不完全确定我理解这个问题。

Answer 1

您的错误消息表明您没有针对CDH4运行Presto，而是针对Hortonworks Sandbox，我认为是Hadoop 2.2.0。此时存在已知的不兼容性。有关详细信息，请参阅Presto Google Group上的此主题：https://groups.google.com/forum/#!topic/presto-users/lVLvMGP1sKE
