Hi ,
As your issue seems to be a specific technical issue you would have better assistance from the community by posting in StackOverflow as Google Groups is intended for general discussion. You should post to StackOverflow with the extra log information to have the developer community assist you.
That being said, the temp_file_limit is a flag you can set. Please try increasing the assigned value and try the import again.
We have 3 ways to configure the flag (i.e. via Console, GCloud, or Curl). Can you please take a look at this doc for the individual methods?
Please also note that temp_file_limit is listed under "Supported flags" section.
