Question

我试图连接到oracle数据库以检查记录数。

Scenario-1:
    [user@hostname ingestion]$ sqoop eval --connect jdbc:oracle:thin:@//hostname_1:PORT_1/Service_1 --username USER --password PASSWORD --query 'select count(*) from SCHEMA_1.TABLE_1'
        class path is /usr/hdp/current/hive-client/lib/libthrift-0.9.3.jar:
        Warning: /usr/hdp/2.5.3.0-37/accumulo does not exist! Accumulo imports will fail.
        Please set $ACCUMULO_HOME to the root of your Accumulo installation.

Scenario-2:
[user@hostname ingestion]$ sqoop eval --connect jdbc:oracle:thin:@//hostname_2:PORT_2/Service_2 --username USER --password PASSWORD --query 'select count(*) from SCHEMA_2.TABLE_2'
        class path is /usr/hdp/current/hive-client/lib/libthrift-0.9.3.jar:

        ------------------------
        | COUNT(*)             | 
        ------------------------
        | 43                   | 
        ------------------------

第一个给我错误，而第二个给我预期的结果。

有人可以帮忙吗？ jar使用ojdbc14-10.2.0.4.0.jar

Answer 1

花了相当一段时间后发现了这个问题。由于关闭的端口，运行Sqoop的边缘节点无法telnet（OS补丁在一周之前完成，并且linux管理员关闭了端口并且没有打开它们）。一旦端口在sqoop运行的边缘节点中打开，我就可以执行sqoop eval

Sqoop oracle连接问题
