Description
NotImplementedError: only support to_csv with mode 'w' for now
Contributor guide
Research direction
Start by tracing the Mars DataFrame df.to_csv entry point and the code that raises “only support to_csv with mode 'w' for now.” Determine how mode is currently handled and identify the relevant existing tests; done means supported non-'w' modes no longer raise this NotImplementedError and the behavior is covered by tests.
