InnoDB error: exceeded log capacity...but only during import
You are probably trying to import very large rows. The 5 MB default log file size (10MB in total for the log) may be too small in many cases. The default for 5.6 is 50MB (100Mb in total), which is probably a more sane default in most cases.

If you do not have much load, the only problem of augmenting the log is having to handle a larger set of files, nothing else should change (this is not true in heavy-write environments). it will also make the load process much faster, assuming you have enough memory size for the buffer pool. You may want to change the innodb_log_buffer_size if you are loading lots of large rows.
