我正在尝试将数据从 csv 文件导入 gpdb 表，但 COPY 命令失败并显示“没有此类文件或目录”错误消息 - 尽管我尝试读取的文件确实存在。
设想
我们正在尝试使用来自名为 SQL server 的源的 Talend 工具将数据写入名为“pivotal greenplum 数据库”的目标系统。
其中，数据流组件称为 tGreenplumBulkExec 抛出
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 --> 写入 hdfs --> tmap--> tGreenplumOutputBulk--> tGreenplumBulkExec
详细的堆栈跟踪

我们尝试了：
Path permission of Input file already checked.
Double checked the file path in talend component setting.
