蜂巢錯誤創建外部表時（狀態= 08S01，代碼= 1）

Question

我試圖創建蜂巢外部表，但不斷收到以下錯誤：

create external table foobar (a STRING, b STRING) row format delimited fields terminated by "\t" stored as textfile location "/tmp/hive_test_1375711405.45852.txt"; 
Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask (state=08S01,code=1) 
Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask (state=08S01,code=1) 
Aborting command set because "force" is false and command failed: "create external table foobar (a STRING, b STRING) row format delimited fields terminated by "\t" stored as textfile location "/tmp/hive_test_1375711405.45852.txt";" 

的/tmp/hive_test_1375711405.45852.txt內容是：

abc\tdef 

我經由beeline命令行界面，它使用節儉HiveServer2連接。

系統：

• 的Hadoop 2.0.0 cdh4.3.0
• 蜂巢0.10.0-cdh4.3.0
• 直線0.10.0-cdh4.3.0
• 客戶端操作系統 - 紅帽企業Linux服務器版本6.4（聖地亞哥）

Answer 1

問題是，我把外部表指向HDFS而不是目錄的文件。這個神祕的Hive錯誤信息真的讓我失望。

解決方案是創建一個目錄並將數據文件放在那裏。爲了解決上述問題，您需要在/tmp/foobar下創建一個目錄，並將其放置在hive_test_1375711405.45852.txt之內。然後創建如下表格：

create external table foobar (a STRING, b STRING) row format delimited fields terminated by "\t" stored as textfile location "/tmp/foobar";
