Question

我正在尝试将数据从csv文件导入到gpdb表中，但COPY命令失败并显示“没有此类文件或目录”错误消息 - 尽管事实如此我试图阅读的文件肯定在那里。

方案

我们正在尝试使用名为SQL server的源代码中的Talend工具将数据写入名为“pivotal greenplum database”的目标系统。

其中，数据流组件称为tGreenplumBulkExec throw

错误：

    tGreenplumBulkExec_1|org.postgresql.util.PSQLException:ERROR: 
could not open file "/path/to/file.csv" for reading: No such file or directory|1

Talend数据流：

从SQL服务器读取 - ＆gt;写入hdfs - ＆gt; tmap - ＆gt; tGreenplumOutputBulk - ＆gt; tGreenplumBulkExec

详细的堆栈跟踪

我们尝试过：

Path permission of Input file already checked.
Double checked the file path in talend component setting.

任何帮助都会受到高度赞赏吗？
