使用python子进程运行sqoop无法识别参数

Question

When I run sqoop export from terminal it runs properly.But executing it from python scripts returns error:

*ERROR tool.BaseSqoopTool: Unrecognized argument: --connect
ERROR tool.BaseSqoopTool: Unrecognized argument: --table
ERROR tool.BaseSqoopTool: Unrecognized argument: --export_dir*

Following is the code snippet:

call(["/usr/local/sqoop/bin/sqoop","export","--connect jdbc:mysql://localhost/temp","--table table1" ,"--export-dir /user/data/input" ,"--username root"])

Assuming imported the subprocess module

Answer 1

The single arguments in your argument list shouldn't contain any whitespaces. The line should look like this:

call(["/usr/local/sqoop/bin/sqoop","export","--connect", "jdbc:mysql://localhost/temp","--table", "table1" ,"--export-dir", "/user/data/input" ,"--username", "root"])
